Comets ISON, Lovejoy, LINEAR, 2/P Encke by Sormano Astronomical Observatory

Welcome again to the Spaced-Out Challenge. Whether you have a question about a scope, a new astronomical discovery you want to expand on, or just want to kick back and enjoy the cosmos above, come one come all on our weekly journey through space and time. This week's edition will be your all-in-one source for catching a glimpse of not one, not two, not three, but four visitors from the Oort Cloud, including the big tease, ISON.

Note: this is a very, very large edition of our astronomy post, with the intent to answer any and all questions you could possibly have on these elusive and exciting icy visitors. It starts with a general background on comets, then details on the four we are targeting, then where to look, then how to photograph them (and win fabulous prizes), followed by an abbreviated buyer's guide for those of you lacking equipment, washed-out sky observing tips, our traditional closing, and finally the full dark sky directory for those wishing to get out for a better look.

The Guts of a Comet
Comets are large chunks of ices and dust left over from the formation of the solar system that "fall in" from the distant Oort Cloud towards the sun. Their prime components are summed up well in this demonstration by Dr. Amy Manzier of the Jet Propulsion Laboratory:

Comets vary. Dr. Karen Meech explains the difference between the short, long, and "fresh" comets, all of which are in the sky above right now:

Visible to the naked eye now from an extremely dark spot, obvious in binoculars, and gorgeous in a telescope, Lovejoy has overtaken ISON as the current comet of interest among amateurs.
It's discovery, the fourth by amateur Terry Lovejoy, was reported back in September on UniverseToday, and initial reports missed it's current brightness level by over a magnitude:
The discovery of C/2013 R1 Lovejoy was announced on Sept. 9 after two nights of photographic observations by Lovejoy with an 8-inch (20 cm) Schmidt-Cassegrain reflector. When nabbed, the comet was a faint midge of about 14.5 magnitude crossing the border between Orion and Monoceros. Subsequent observations by other amateur astronomers peg it a bit brighter at 14.0 with a small, condensed coma...And as Stuart Atkinson noted on his website, Cumbrian Sky a great lineup should be in the northern hemisphere skies on November 9, 2013. From the left, Comet Encke will be magnitude 6, ISON should be at about magnitude 6 or 7; then Mars, followed by the new Comet Lovejoy, which will be still very faint at around magnitude 9, topped off by a bright Jupiter. The comets will not likely be of naked eye visibility, but this should be a great chance for astrophotographer to capture this lineup!

Tony Flanders recently observed all four of these comets from a site in suburban Boston, and was most impressed with Lovejoy:
Comet Lovejoy (C/2013 R1) is a real humdinger — almost as bright now as Comet ISON was forecast to be -- which is to say, about 10 times brighter than ISON actually is. This morning Lovejoy was in the same binocular field of view with M44, the Beehive Cluster — an incredible view. The comet is big, bright, and gorgeous, with a diffuse but fairly long tail.

Moreover, Comet Lovejoy C/2013 R1 (not to be confused with other famous comets discovered by Terry Lovejoy) is very well placed in the predawn sky, high in the southeast near the Leo/Cancer border. If you prefer staying up late to getting up early, Lovejoy is reasonably high in the east by 1 a.m. at mid-northern latitudes.


Naked-eye visible now in exurban and rural skies, can be seen with binoculars in any sky.

Comet 2P/Encke, Old Faithful

Comet 2P/Encke, first discovered in 1786 by Pierre Méchain and recognized as a periodic comet by Johann Franz Encke in 1819, holds the record for the shortest period of any known comet at just over three years. Comet Halley by comparison makes an appearance every 75-76 years. Encke never becomes spectacularly bright, but makes for a great binocular target, currently at magnitude 7. Universe Today explains why this years' apparition is so special:
this year’s apparition of Comet Encke is especially favorable for northern hemisphere observers. This is due to its relatively high orbital inclination angle of 11.8 degrees and its passage through the morning skies from north of both the ecliptic and the celestial equator. Encke is about half an A.U. ahead of us in our orbit this month, crossing roughly perpendicular to our line of sight.
Note that Encke is also running nearly parallel to Comet ISON from our vantage point as they both make the plunge through the constellation Virgo into next month. Mark your calendars: both ISON and Encke will fit into a telescopic wide field of view around November 24th in the early dawn. Photo-op!

As of this writing, it is the second-brightest comet visible. From Tony Flanders' observations:
Comet 2P/Encke is painfully low at the onset of astronomical twilight, but also quite handsome. Its head is considerably smaller but brighter than ISON's, standing out well against the brightening sky.

Comet C/2013 X1 LINEAR explodes on the scene

Comet-2012-X1_by-Teodorescu_10-22-2013_800.jpg

LINEAR was never expected to become anything spectacular, and it's very low proximity to the horizon will still make it a difficult one to tease out, but it underwent a spectacular explosion on October 22nd, jumping from magnitude 14 (too faint to see with an 8" telescope) to magnitude 8 (visible in binoculars) overnight. The British Astronomical Association has a great compilation of images that show the dramatic flare up that earned this wanderer a spot on this special edition of Spaced Out Challenge. Photographers, now is your time to catch it: the outburst will begin to subside and it will begin to fizzle. It is the most difficult comet to catch of the four, and a blunt Tony Flanders, in the aforementioned article, named it as the one to skip if you had limited observing time.

Comet C/2012 S1 ISON: the Great Tease

Michael-Caligiuri-Caligiuri_ISON_110313_1383934916_lg.jpg

Photo by Michael Caligiuri

Let's go back to September 2012, when Sky and Telescope writer Kelly Beatty did his best to contain his excitement over it's initial discovery:
It was first spotted as a faint, 18.8-magnitude object in images taken by Vitali Nevski (in Belarus) and Artyom Novichonok (in Russia) using a 16-inch (0.4-m) reflector that's part of the worldwide International Scientific Optical Network (ISON). "We could not be certain that it was a comet," Novichonok explains, "because the scale of our images is quite small [2 arcseconds per pixel], and the object was very compact."

The next night they confirmed its cometary nature using the larger reflector at Majdanak Observatory in Uzbekistan, but by then other astronomers had done likewise. According to naming conventions established by the International Astronomical Union, that one day of uncertainty led to the comet being generically named "ISON" instead of "Nevski-Novichonok". Its formal designation is C/2012 S1.

Naming uncertainties aside, we already know a lot about this object, thanks to two sets of prediscovery images dating to last December and January. The comet is inbound from the Oort Cloud and will pass very close to the Sun — just 725,000 miles (1.2 million km) from its white-hot photosphere — on November 28, 2013. Before then and thereafter (if it survives perihelion), Comet ISON could put on a spectacular show.

In fact, the geometry could make C/2012 S1 a "dream comet," as one eager skywatcher has commented, because it will swing just 40 million miles (0.4 astronomical unit) from Earth a few weeks after perihelion, when it will be high in moonless, northern skies after sunset. Initial predictions by the IAU's Minor Planet Center suggest that Comet ISON could peak at magnitude –10 or brighter at perihelion (when it will be just 1° from the Sun), and that it could remain visible to the unaided eye from early November to the first weeks of 2014.

And then, it failed to brighten as initially hoped. However, comets by their nature are extremely unpredictable, and S&T's senior editor Alan MacRobert felt compelled to set things straight on the known knowns, known unknowns, and unknown unknowns regarding the Great Tease of 2013:

Finally, in the last week or so, ISON has finally begun to brighten, with a current magnitude estimate of around 8, placing it well within range of binoculars from dark sites (see the end of this thread for such places). It's peak brightness remains a mystery, as will it's fate when it skims dangerously close around the outer atmosphere of the sun at the end of the month. It could break up and form a wondrous spectacle in the sky like Comet Lovejoy in 2011, or it could fade off into the darkness. We simply won't know for sure for another three weeks. In the meantime though, it is making for a steadily improving and impressive sight in backyard telescopes.

From Flanders' observations:

ISON...has indeed improved a lot in the last few weeks. I swept it up easily in my 7-inch Dob at 28X, and it was quite handsome at 120X, with a 3' head and a bright, starlike pseudonucleus. I didn't see any sign of a tail. I tried and failed to see it with my 10x30 binoculars; it might be possible in a darker sky [again, Flanders was observing from suburban Boston]... I think that ISON should be pretty easy to spot in a telescope now from a typical suburb, assuming you have a low eastern horizon.

Binocular object from rural and dark skies, visible now in small telescopes from any sky, brightening to at least a binocular object from any sky by months' end.

Where to Look
Up. More specifically, these comets will be best seen in the morning pre-dawn and twilight hours, as they dive closer towards the sun. Comet ISON will be at its most brilliant the day after Thanksgiving, but will be to close to the sun to see practically.

CometsGaloreWideMap.png

Greg Crinklaw has an unbeatable chart of the exact where-when-what for looking at all of these comets, including fantastic PDF finder charts I will link directly below. Simply orient yourself towards the East, refer to these charts, and start hunting. Can you catch all four?

Photographing the Comets & Various Contests
I'll admit my knowledge with astronomy is limited to just the visual side, but that doesn't mean I can't forward you to the most extensive guide to photographing a comet you'll ever come across, courtesy the Waiting for ISON blog. So no excuses for you Walt. Get on it.
Even if ISON proves a fizzler, if you've got a camera and want some green, there are multiple contests with fantastic prizes worth entering.
Sky and Telescope offers an 8" Celestron EdgeHD as it's grand prize.
UniverseToday & OPT offers an assortment of prizes, top of which is a fantastic all-in astrophotography bundle.
Lastly, Discover Magazine and the National Science Foundation are offering cash prizes for top pics.

Abbreviated Buyer's Guide
The extensive Beginner's Buyers Guide has even more to offer, but I'll recap on a few potential buys for catching the comets.
Binoculars
There are several cheaper options on the original buyer's guide, but several readers have been wowed by these:

opplanet-65803.jpg

Pentax PCF II 10x50 Waterproof Binoculars

$160. Excellent, excellent, excellent binoculars, especially for the price. From the feel to the surprising light weight to the high-performance optics, if you have the scratch, spend it. They easily out-perform binos selling for three times as much, but that's Pentax for ya.

Telescopes
The scopes listed in the original thread are all still great, but here's some new additions the list, and a price drop alert for ya.

Orion's Star Blast 90mm Altazimuth Travel Refractor


$199, shipping November 26th.
While I haven't tested it yet, Orion's 90mm refractors have been decent peformers, and the alt az slow motion knobs and decent tripod will make for a fantastic grab-and-go.

A Good Scope for Kids: Orion's GoScopeII 70mm Travel Telescope


$80 shipped from Amazon
The kid in the video tells it all: light, compact, easy to use, and powerful for a scope of such small size.

Orion XT8, which is on sale, so seriously buy the damn thing

ORIONXT8.jpg

The Orion SkyQuest XT8 Classic


The best introductory amateur telescope sold in the last hundred years. Tough. Large. Extremely easy to assemble and use. Highly adaptable. Intimidating to your neighbors.

To update from my original gushing pitch on, hands down, my favorite telescope out there, it is now selling for just $330 shipped. Best bang for the buck, but remember: it's a big lady.

CBD alerted me to a sale on Costco for the Celestron 130EQ telescope. Normally I'd say pass, but for $160 shipped, they also throw in a half-decent accessory kit, so not bad for a "department store" scope. Celestron's "Costco 102" is unfortunately no longer available (though you can find one if you're lucky on eBay from time to time), so this is the best I've seen advertised for such stores.

Eyepieces and Fliters

Astro-Tech 1.25" Eyepiece and Filter Kit

$130 shipped from Astronomics. There are a few "beginners kits" out there, but none have the bonus of a great "wide-field" eyepiece and at least two with great eye relief. Included eyepieces are 6mm, 9mm, and 40mm plossls, and one 15mm 68degree Superview. Four colored filters for aiding planetary observing, a moon filter, and a barlow lens round out the kit. The 6 and 9 mm have only 3mm of eye relief, but the rest of the kit more than makes up for this shortcoming.

Lumicon's Comet Filter

31ROwK7kf5L.jpg

$130 from Amazon/AgenaAstro
Cuts through some of the clutter and improves viewing of the coma and tail. Also comes in a 2".

Zhumell Z Series Planetary Eyepiece Kit

$170 shipped from Hayneedle
Planetaries that rival eyepieces costing 5x as much, with a padded carry bag?. The Z series offers nearly an inch of eye relief, 55 degrees of apparent field of view, and have gotten rave reviews from the amateur community.

Comet Viewing for Urban Observers
As Flanders had indicated, getting away from bright lights is ideal, but not necessary for enjoying these visitors now through December. Blocking stray light will make teasing them out of the sky a lot easier, along with getting your eyes dark adapted. I've reposted a few relevant tips and tricks from the original Washed Out Sky post, and included a painfully easy one I plumb forgot:


Get Your Eyes Adapted
Our eyes have an incredible ability to adjust to darkness. After a good half-hour from a very dark site, we can even eyeball Uranus, which rarely brightens beyond magnitude +5.7. The same holds true in urban environments, if we protect ourselves from bright lights. I suggest buying Orion's AstroGoggles:
Orion AstroGoggles.gif

At only $19.99, they help your eyes adjust and stay dark adapted even when checking your cell or walking inside the house for a coffee. Oversizing makes them an ideal option for eyeglass wearers. You may look a member of DEVO wearing them, but nobody said astronomy was high fashion.

Build a Light Barrier

effOFFneighbors.jpg

Eff off, neighbors!

If you live off a busy street like me, the constant stream of cars can make a long night of observing a headache. Or perhaps you have that neighbor who insists on leaving his floodlights on. Building your own portable light shields is a cost effective way to eliminate these sources of nuisance light. John Duchek at CloudyNights has a great step-by-step build guide for making your own light shields. I've modified it a bit to include his "updated" bits (they were a work in progress with his initial publication) and current prices for all required materials. You can make four of these light shields for less than $100 and they are incredibly effective:
When I can get fully dark adapted, I can see magnitude 5.2 stars from this site so the sky can be seen reasonably well if the light trespass from the neighbors can be blocked. In addition cars pass by at irregular intervals. To stop the light trespass, I have built 6.5'x 5' light shields at a cost of about $10-15 each. The first one is somewhat more expensive since you may have to buy the "general equipment". Each takes 1.5-2 hours to build if all parts are present...
Initially, three of these devices have been successful at shielding me from all of the lights above and all car lights going by my house. I can now remain with dark adapted eyes for hours in my neighborhood...
To build a 6.5 foot x 5 foot light shield, you need the following:

General equipment:
Can of PVC cement $4.50 (good to make many light shields)
1 roll (10ft x25 ft) of 3 mill black plastic sheeting (enough for 8 shields) [$10] Some of the black plastic I saw was not opaque and let a little light through. Check that it is opaque before you buy.
Hack saw [$7]

For each shield you need the following:
3 x10ft pieces of 1" PVC pipe $10 total
4 x1" PVC Tees $2.50 total
2 x" PVC 90 degree elbows $1.20 total
15 inches of Velcro tape [buy industrial grade $8-$18]

Directions:
Cutting:
Cut 1 PVC pipe into 2 x 5'0" pieces
Cut 5'7' pieces from the other two 10 foot pipes
From one of the 4 ' 5" remnants, cut 2 x 6" pieces and 3 x 1 foot pieces
From the second remnant, cut 1 additional 1 foot piece
Gluing:

lightShieldPipes.png

Glue 90 degree elbows to each end of 5 foot section (be sure they point same way) (Piece #1)
Glue the center hole of tee to each end of the other 5 foot section (be sure that they line up parallel as in picture) (Piece #2)
Glue 2 1 foot section in to ends of 3rd tee
Glue 2 1 foot section in to ends of 4th tee
Glue 6 " piece into center hole of parts from step 3 and 4 (Piece #3 and #4)
The two 5'7" pieces are pieces 5 and 6.

Once the glue has dried, the frame is assembled. I put a very small amount of grease on the unglued joints to be sure I can easily separate them when desired...[cut 12 1" strips of velcro] use a good contact cement, paint on both the pipe and back of Velcro, allow to get tacky, and press together. A rubber band is useful to hold the Velcro fast until it has completed the drying process...
Assemble the frame as in the pictures. Here is a picture of a completed single frame unit.

LightShieldComplete.png

Cut a 6 foot piece of the black plastic off the roll. Hang the strip (it is 10 foot wide) over the frame so that both sides are equal. Cut the plastic sheet in half. This gives you two 6 foot x 5 foot sheets. [Line up] one of the sheets (five foot part horizontal) to all 12 strips of velcro, [staple identically sized velcro strips to light shield frame, line up,] and your light shield is complete. You may or may not wish to trim the bottom inch or two off the bottom of the sheet. (mine drag the ground by about an inch and keep ground level light our nicely.

Light barriers can be built with more durable materials, but if you're on a budget, 3mil and pvc can't be beat. If your own outdoor lighting makes observing difficult, Lowes now offers IDA-approved dark-sky friendly lighting mounts that can greatly improve your backyard sessions too.

Protect Your Instrument from Stray Light

LightShield_1a.jpg

Washed-Out Astronomer's $5 Shield

Reflector telescopes often have the secondary mirror and focuser close to the open end of the telescope. This puts both at risk of being impacted by stray light. A simple solution to this is making yourself a "light shield" that effectively extends your telescope tube and eliminates this risk. The Washed-Out Astronomer offers this great $5 DIY light shield project:
Step one is to acquire or fabricate a rectangle of black poster board paper of the appropriate size. The end ring of my telescope tube has an outer circumference of 38.5 inches. Allowing some excess for gluing, I needed a rectangle of poster paper about 42 inches wide. The common wisdom is that the front of the telescope tube should extend a full tube diameter beyond the focuser. So for my telescope that meant the rectangle should be at least 12 inches long.
At the local arts and crafts store, I found sheets of 22 x 28 inch poster board paper. I glued two of these together to make a 42 inch wide sheet. I used ordinary white glue to join the sheets. Don’t make the overlap too big and apply the glue evenly but sparingly. Otherwise the overlapped section will be rather stiff and hard to shape into an arc of a cylinder (I overlapped about 3 inches). Be sure to join the two sheets squarely. After the seam dried, I overlaid the each side of the seam with packing tape...
After gluing, I had a 42 x 22 inch sheet...I then shaped the big sheet into a cylinder and glued it. To hold it while the glue set, I used clothes pins to clamp the top and bottom of the seam, added a little tape in the middle, and then laid the cylinder, seam side down, on the floor with a couple of liter bottles of water inside the cylinder on top of the seam to keep pressure on it. Once the seam was dry I again taped it on both sides. To keep the cylinder ends from fraying, I also taped the rims all around. It was almost finished—almost, but not quite.
The final step was to try it on for fit. My intention had been to have the extension tube fit snuggly around the top end ring of my telescope and have it rest against the four "nuts" that anchor the secondary vanes. Unfortunately, the fit was a bit too loose. To make it a snug fit, I originally planned to line the inside bottom area of the cylinder with foam. But then I realized that the fit was loose enough that I could actually wiggle the extension tube over the tops of the four spider vane nuts. That made for a really snug fit and locked the light shield in place very tightly. To keep the nuts from eating into the poster board, I put some tape strips on the inside of the cylinder at the four spots where the nuts rub against the light shield. The smooth tape surface also makes it easier to slide the light shield on and off.
Finally, I marked the outside of the cylinder with white and red crayon (borrowed from my daughter) so that a red flash-light will highlight the taped areas on the light shield. This way even in the dark I can easily align the taped areas with the four nuts. The crayon markings are clearly visible in the photo below showing the light shroud fully seated on the telescope.

WOA lives in suburban D.C., so his site is a must-read for budding astronomers living under less-than-ideal skies. The full step-by-step guide for his shield is here.

Wear an Observing Hood (or a towel)

IMG_7299.JPG

Dark Skies Apparel Observing Hood

So easy, I completely forgot it. If building a cheap light shield is too much of a hassle, grab a large, dark towel, and simply don it while observing through your telescope. It may become clumsy navigating around your observing space, but whatever works. Observing hoods are sold online for about $35, if your pocket has any money left to burn after scrambling for optics.

Dark Sky Sites for All 50 States
Regular reader and photographer Matthew Gowan was inspired by the original Perseid thread featuring this list, and decided to track down that dark sky spot in Central Florida I had mentioned, and this was the result.

To save you the hassle of jumping to an older thread, here is the original directory:

AOSHQ Dark Sky Directory

While nothing can beat an immaculate night sky, the experience of these flashing visitors streaking through the summer Milky Way can be enjoyed within a reasonable driving distance wherever you may be, weather permitting. Many states and towns have dedicated parks as "dark sky preserves" and are more than willing to accommodate the needs of local amateur astronomers.

If you're saying I have a chance of seeing some coolness, I'll wait on burning leavez and sticks. I'm in Norfolk, but have an acre, and can get to a pretty dark spot in the back forty...

I am really going to make an effort to pay closer attention to the night sky when we go up to our cabin in the Upper Peninsula. Your post says the Hiawatha National Forest is the darkest spot in MI. That's where we are and I can attest to the fact that the stars from there are full of overwhelming awe.

My daughter is the star-gazer in the family. She will sit outside by the campsite all night long.

Yeah, was a Christamas gift to the better half from her mom last year. Within 2 months, he became "my dog." Just over a year old now. I can't be positive, but I think he might be "special," if you know what I mean. He would rather eat pine cones, carrot scraps, celery or ice than dog chow. And he answers to "poopyhead"

As an aside, Dr. Amy looks like she may have pointy elbows - I don't know if I trust her.

31 The last forecast for GOCE re-entry I heard was between 5:50 and 7:50 pm EST. We're already past the midpoint of that window, so it should be happening any minute now.

33 The coming of a comet is supposed to be a harbinger of apocryphal events, at least that's what our medieval ancestors thought.

Enke is probably not from the Oort cloud (this time) as it's period is too short.

Deer season is coming, I'm going to reclaim the refractor scope from the parents house (where it's been in storage.)

Attempt to find the replacement angular mirror, and then take it out to deer camp which is just west of CAC's "magic spot" (so one light classification higher than "Darkness."

160 acres of nothingness, surrounded by 300 acres of conservation land.

I'm not sure if I'll be up to see the comets, it depends on how the hunting goes. (If it goes well on day one or two, I may just stay up all night stargazing.)

52 Mind if I ask? I have a 4" reflector that needs the mirror aligned. Some visiting Einstein messed with the settings and I figure I could probably realign it with some help, so I wondered if any of you guys knows of someone in SW BC Canada that can either walk me through it or even fix it if it comes to that. It's an inexpensive reflector (Omcon 811EX?) but it is a gift from someone that expects to see it displayed prominently if you know what I mean... I won't mention any names but her initials are the mother of the Ministry of War and Finance, aka Mrs TrueNorthist. It has three nyloc nuts on studs that are connected to the mirror and it is way out of whack.

Can anyone help me out here?

Posted by: TrueNorthist at November 10, 2013 08:35 PM (3Aixx)

53 FWIW, i also downloaded google sky maps. Kinda cool. As a novice, it looks like it will help (and maybe marry nicely with the SkyWeek app) - i can sit here in the house (or on an overcast night, outside), point the phone anywhere, and it'll show me what should be there.

Some reviews said it was off, but it's overcast here right now and i can see the moon. App showed it exactly where I see it through cloudcover.

76 Sigh. I really, really want to observe a comet. All the time I was scoping there were SFA. When something actually showed up in recent years, it was cloudy, raining or I was working at night, or something. The bloody things have never played ball. Now the northern hemisphere ppl get a whole bunch at once. Bastards.

77 "By the time you read this, the spacecraft's amazing flight will, most likely, have come to an end," spokesman Daniel Scuka wrote in an update posted around 6:45 p.m. on the agency's website.

Yeah, I saw that. I haven't heard anything since then, though.

Soyuz's parachutes have deployed.

I'd haul my ass out of bed to see a decent comet by naked eye. With a scope even better. You're supposed to able to see something of one at least, down south, but you've got to be out in the flat desert or something. Halley's was a bust. Couldn't see shit in the city.

83 A beuatiful morning in Kazakhstan, but below freezing. The astronauts are being placed in chairs and wrapped in blankets.

And the Olympic torch is out!

I was hoping for a method that gets around using a laser, but it looks like that is not a viable option if I want the thing to actually work effectively. The primary mirror does not have an alignment circle and is very, very dirty so I think a complete tear down is warranted. It's a very simple Newtonian design which makes the job a bit less intimidating.

Thanks CAC.
