I barely pulled ISON out of the light dome to my east yesterday morning with an Atik Titan and 8" LX200. It would have been a hopeless case visually. I've been watching for it with the camera for a few weeks. Actually as it turns out I started looking the same day Bruce Gary recovered it, but I didn't have any success until last week.

So has anyone seen comet ISON yet?

I went out sat night for an all nighter, with my 180mm APM/TMB F6 refractor and a friend was using his LX-200 12" Meade SCT and we were hoping to get an early morning chance to hunt down Comet ISON but it was just too low for us to find. The Atmosphere that low that early was more than the seeing would allow. We just barely was able to pic out Mars and the Beehave was almost invisible, despite the skies being clear. Too bad for us.
We are gonna keep trying in a few weeks when ISON should be up sooner, hopefully it will get above the morning "muck" so it becomes visible.

Anyone else giving ISON a try now? Its time for the larger scopes to start picking it out under darking skies. New time I'll probably try it with my C14 if the conditions seem favorable. Currently, its touching the eastern horizon right at 3:30am, so another month from now it will be up about 2 hrs sooner and visible in smaller scopes.

Good luck to anyone giving ISON a try. I had lots of fun with PannStarr and Lemmon, now its ISON's time.

I went after ISON this morning from a gray zone site (4500 ft elevation, Limiting Magnitude 7.0 at zenith). There was a little bit of scuzz (residual forest fire smoke) around the horizon, but ISON was well above it by 5am at my latitude of 42.6 degrees. The zodiacal light did brighten the sky a bit.

I starhopped to the field from the Beehive at low power and since there were only a few minutes of astronomical darkness remaining I went right to my 7mm Nagler (165x). I probably should have used 76x instead, but I wanted to darken the background as much as possible and I expected ISON to be small and condensed and possibly in need of higher magnification to be revealed as nonstellar.

The seeing was a bit nervous, but not too bad considering the low elevation (15-20 degrees). My finder chart (printed from Cartes du Ciel) wasn't too precise, so I stumbled around the field a bit. A magnitude 14 field star caught my eye first as looking a bit nebulous (later, back at the computer I saw that it was double, which probably contributed to that effect). After a few minutes, I picked up ISON as a ghostly smudge that was larger than I expected (about 1.5' in diameter). The comet was just a couple of arcminutes WSW of a magnitude 11.5 star.

I followed ISON for about 20 minutes before twilight blotted it out. The comet appeared slightly elongated to the NW (PA 290), pointing toward a field star of magnitude 14.5. The coma seemed just slightly brighter in the middle, with no definite nucleus (the mediocre seeing may have affected my impression).

I didn't make a formal magnitude estimate. I'll try to view the comet again tomorrow morning.

A slightly prettied rough sketch is attached.

Nice report Wes. Its fun when they first start coming into view. I remember being very young and doing this with Halleys comet and have observed ever comet since then that was visible with the gear that Ive owned.
I'm looking forward to some nice visuals. Not a big fan of Photoshopped photos, so the sketches and reports are much more favorable than photos to me.
I'm a big fan of seeing the concert live, not on TV.

Congradulations!!

Thanks for the report and sketch. Comet is still too low
for me to observe / image at my local where twilight begins
at 5 AM. At 5:30 AM comet is only 21 deg. up. I need about
30 deg elevation to see over the tree tops I might be
able to see it in two weeks time. Keep those reports coming
and thanks.

Ok so Regulus and Mars will be observable but ISON will be drowned out by the others



I didn't mean that I'd be trying to see all three at once with the naked eye. I assume you're NOT saying that ISON will be drowned out when using a telescope to view all 3 at the same time.

Wes,

Great observational sketch and report. I'm like PJ--the view to the east from my observatory is blocked by a ridge to ~20 so I'll have to wait to put my big Cat on ISON. Unfortunately, in a couple of weeks the waning Moon will be a factor. Patience...

I agree--very nice, John. ISON has that "classic" comet look right now.

I wander if I can reel this in visually with my 17.5" ?

Thanks for posting images John. Great to have a record of
comet changes as it loops by us thru the solar system.

That's an excellent site, thanks for the heads up on that. That's all we need to know, as to were to look for it.
I'm looking forward to looking for it now, every Saturday night that I find clear with no moon in the sky when it comes up. I'm not able to get any of my fair weather astronomer friemds to come out with me that early so I'm on my own on this one. Its still pretty fun. These are the best times to find it, when you actually have to be an astronomer and look for it with charts, diagrams and computer programs.
These are the fun times which separates the passionate ones from everyone else.

Again, great site. thanks again!

That site you posted, and:

http://www.calsky.com/cs.cgi

are excellent for locating exactly where ISON is located in the sky, even if one does't have Stellarium or something alone those lines, It seems to be about 2 degs from Mars tonight.
