Thanks for posting...great images and I do like the
comparison showing how this comet is developing.





You are most welcome. I love seeing this comet progress and I imaged it everyday since last Thursday until Sunday morning, when weather conditions changed for the worse and put a stop to my efforts.

Sunday's data was only so-so, since the murk was extra thick that day and the moon didn't help matters. It was too noisy to use to make a close-up image. I made the best of the situation by taking the data and making another comparison image, this time with the moon. Check it out:



The moon was taken with the same equipment and is actually a first quarter moon flipped to match the phase of the moon that was out Sunday morning. LoL.

This is the full frame of my imaging rig. I'm hoping that before its all over, ISON won't fit inside the frame because it will get too big! Now that would be awesome. lol

Nice one Mike- I think you captured a couple of meteor impacts on the moon as well

LoL. Yeah, its a meteor storm from ISON. (Cue the woo-woo music.)

Well Mike, when you "make the best of the situation" you sure know what you're doing. It has an awesome 3D look to it. Thanks!

I'm pretty happy to see the Moon fading away. I haven't made an attempt to see the comet since my failed attempt on Oct 15 and I'm excited to try again. Does anybody know what the magnitude increase has been since then?

Very little I'm afraid, and mostly due to the comet's decreasing geocentric distance. ISON was reported as a little fainter than 10.0 at mid month and the latest reliable sightings put it in the mid 9's.

Thanks for the warning Brooks. I suppose it's still worth a try. A half-mag increase might be all I need to pick it up with my 10 inch.

Image taken on the morning of 28 October. The moon did not
seem to be too much of an issue and the later morning
twilight sure helped in getting more subs as I have to wait
for the comet to climb above 28 deg altitude to clear the
tree tops.

I shot it on the morning of Nov 2nd, 2013. ISON was rising out the trees and I started shooting it with great expectations that I'd get lots of good data.

Unfortunately, clouds invaded and I had to throw out more than half of what I shot. What was left was lots of LP ridden images and quite a few subs with tree branches in them, since the early subs caught it rising out the trees before the clouds came.

Anyway, you can get the basic idea of how it looked:



ISON seems to be getting bigger but I don't think it is getting any brighter. In fact, since the light is spread out more, it could be even dimming down somewhat.

Mike,
You have provided better updates on ISON with your photos than I've seen anywhere else, so thanks for that. My question to those who understand comets better than I do, which is just about everyone here, is if ISON is going to live up to earlier predictions, when will we see it? Before perihelion, post perihelion? Thanks.

There's a nice guide in the current Sky and Telescope issue. Basically, it's a morning object until late December. It will get brighter as it nears the sun, but it will be harder to see in the glare. If it breaks up before perihelion, there may not be much left to see. If it breaks up after, it could put on quite a show. It's anyone's guess right now (and a lot of people are trying to guess )

Great images to date Mike. For interest I did a crop /
resize / lowpass filter / tangent histogram stretch on
both C/2012 S1 and C/2013 R1 nucleus. Interesting to see
how tight and basically round the nucleus of C/2012 S1 is
versus a very convoluted shape for the nucleus of C/2013 R1.
I don't know how this relates to comet activity but
C/2013 R1 certainly is putting on a better show right now
than C/2012 S1.

ISON this morning was bright and easy to see in my 10" under mediocre sky conditions. I would estimate the brightness is at least mag 8.0. Slightly oblong coma about 2' in size, but no tail seen due to brightening dawn sky and high clouds.

If it hadn't been hyped, would be be so concerned with it? Observations I made yesterday morning made it hard to believe it could possibly become a great comet - but I know it'll be getting warm in three weeks, so I am keeping my fingers crossed! Glen

Does anyone have or know the data needed to key ISONs data into an Autostar hand controller?

Thanks, Rocky. Getting comet images is what I live for. lol Glad my obsession helps out other people, too.

I don't make predictions, but I say any comet with a tail is a good comet. Now, if it holds together and performs like McNaught or Lovejoy did with a tail so long it won't fit in some of my wide angle lenses, that will make it a great comet. LoL. So, pray that it holds together until after perihelion.

Now, for my next update, I present my best image so far of Comet ISON from Sunday, Nov 3rd, 2013:



Looks like its longer than the moon's diameter, now. Perhaps just a tad shy of 40'. That end portion is very dim, though.

Thanks for another great image Mike.
The clouds here in Pennsylvania are killing me but I can always depend on your latest work of CCD art.

Beautiful images, Mike. Thanks for sharing them. I made an animated gif taken from within the light polluted city. 25 frames, each frame 80 seconds (4 x 20 s) to show the movement. I had to compress it quite a bit due to the maximum file size requirement.
Any suggestions on how I can improve it are appreciated.
