I just came in now at about 0230UT. The view in the EP is much like katodogs images. Tonight the central core is a bright point of light on the south side of the inner coma, seems to be pretty well centered in the whole. The whole north edge of the outer coma seems much less distinct than it was Thursday, while the south half still seems to have a well defined boundary. I think I see a faint gray-green color.

I was out eyeballing the sky between sunset and moonrise tonight (sunset: 5:58; moonrise 6:26), and was surprised to see how easy it was to spot the comet in the blue twilight sky. I could easily see that it was diffuse, too.

It was worth setting up the AR-6. I didn't even do an alignment and must have done something right because when I slewed to Holmes it has stayed in the field of view now for over 1hour. This is fantastic! My first comet through an ep. I missed last years round with McNaught due to cloudy skies and I gotta tell ya, this makes up for it grandly. My wife looked at it thought the Meade 5K 24 UWA and the first thing she said after Wow! was that it looks like a dandelion. I had to agree. However you may describe it, it sure looks beautiful. Back to the ep!

It cleared here last night about 3:00 right before I went to bed. I decided to go out and have a look through the binoculars. Before it was over I sat up the 8" SVP to have a look and it was 5:30 before I knew it,it was well worth it. I also set it up tonight and it looked wonderful before the Moon came up. After it came up I did notice that it didn't look as bright as it was yesterday but thought it might be my imagination. I am glad to here it is not my imagination but not that it may be coming to an end!

Dave,
That clearing line hit here a bit after midnight. And it was worth the wait. I saw the comet around 1:30 a.m. with the 25x100s set up:
Oct 28.23 UT: m1 = 2.5, Dia = 3', DC = 8...NE...Phillip J. Creed (Canton, OH) [It just gets better and better! The coma has grown significantly in size since my last observation 2 nights ago. It is not stellar upon close inspection with the naked-eye.
In the 25x100s, again, I'm at a loss for words. I really wish I could see this thing in a telescope! (I kinda picked a bad month to have the 16" mirror recoated!) The comet has a faint outer halo that's now ~14' in diameter. The bright inner coma extends out ~6', with a n intense central condensation that's ~1' in diameter with a distinct "nucleus" (or pseudonucleus) imbedded within. It's like peeling away an onion layer after layer!
Two nights ago I saw what looked like a dark "shadow arc" on the NE quadrant. Tonight I could see the arc, but it looked like it encompassed the entire inner coma, roughly halfway between the nucleus and the inner/outer coma boundary, or about 3' from the nucleus. It was still most prominent along the northern and eastern sides of the comet, but it really stood out tonight.
The nuclear region itself had a starlike "nucleus" that was offset from the central 1'-diameter condensation; much of this central condensation was offset to the SW of the nucleus.]
Clear Skies,
Phil

here you see the direct comparison:
  
  
all of them ISO400, 10x30sec, 30darks.
Here you have the comet and the delta star both in a single frame:
ISO400, 35darks, 30x30sec.
All of them: William Optics ZS80II ED, WO flat-2, Canon Xti, Orion Sirius-EQ. from my backyard in Tucson,AZ.
done with 80mm, now I am gonna go to the 21". :P
thanks for viewing,

Took this tonight. ISO200 for 25 seconds with a Rebel XT and 80mm scope. Seems to be a green hue surrounding the comet. anyone else seeing this?
yes...i noticed this as early as Thurs. night thru the new Vixen ED103SWT Apo...the halo, or outer coma, appeared to have a very faint greenish color to it...barely visible but there...i`ve notice this greenish color darkening into a greenish/grey and showing up more and more in the pics which have been taken.

Phil,
I was out polar aligning at 11:15, the clearing line came
through earlier than CSC indicated it would, gota love that
Goes-12 satellite.
I got around 5 gigs worth of shots tonight, i could see
the arc your talking about in the sub frames on the camera
when i zoomed in, looked like a dark backwards C.
This thing is just awesome!
Tomorrow i`m going to mount the 10" for some visual and
imaging, stop up and take a peek if you want.

John Wunderlin,
Thanks for posting your excellent set of images--it's interesting to compare them to Phillip Creed's report.
The clouds are finally going away this AM and I hope to get to see 17P/Holmes for myself this evening. In the meantime, thanks again to everyone for posting your observations.

Thanks Jim. I took some pics Thursday night as well but none showed the green color. I may have to go back and look again.

like so many others, this comet has been a real thrill. The only problem has been the bright moon. Or so I thought. Holmes is so bright and easy to find it is no problem but while looking at the comet something strange happened. A big flash of white and when I looked away from from the eyepiece there, way up several thousands of feet, in the bright moonlight were about 40 white pelicans migrating through but spiraling in a big circle and appearing right around the comet for 30 seconds or so and then drifting off to the south. Very bright in that moonlight of the 26th, and adding to the magic and grandeur of this interesting and incredible comet!

In a post above Carol L mentioned the interval between sunset and moonrise she has. At my place where the sun is setting now is a wall of 13000 foot plus rock and where the moon rises happens to be low, only about 6° above the horizon. But, both the newt in my OBS and the refractor mounted about 150 feet SW are blocked for a good while to the E & NE
I do have an idle 5" SCT and Vixen GP I think I might just set up for this occasion out where my view is clear because during the interval, in binocs the comet just jumped out at me.
Hmmm- better get busy.

Clouds are my major hinderance on Saturday night, Oct. 27,2007. It was with great pleasure that at least three occasion during the evening and morning hours the clouds parted long enough to view comet Holmes with 10 x 50 binoculars. Even with the moonlight I could trace the sharp outer coma with easy, and the bright inner coma. The inner coma was offset from the outer coma. To my eyes I picked mostly a dim blue in the outer coma, and more white inner coma. The starlike pseudonucleus cound not bee seen in binoculars.
Magnitude was 2.3, using Alpha and Delta Persei for comaprison stars. All of there were in the same 5 degree FOV of the 10 x 50 binoculars.
Fairer weather expected for Sunday evening.

It must be my urban skyglow (NELM about 4.5), but my magnitude estimates for the comet seem to be consistently dimmer than most others. I see it as about mag 3 for the last two nights.

Report from Maryland, south of Baltimore, from Saturday night (10/27/2007)
Naked eye view: the comet was clearly visible to the naked eye as an "extra star" in Perseus with a distinct yellow coloring. May have been slightly "fuzzy" like the Orion Nebula, but to a small degree.
Binocular view in 10x50 binoculars: Comet Holmes showed up as a large, round ball of golden light, almost like a huge, unresolved globular star cluster.
View at 92x in my Orion XT8i: A lot of detail can be seen. The outer circular halo was strangely "bubble-like" in that the outer edges were slightly brighter than the inner region. The outer halo rapidly brightened in the core region to a strong yellow glow. Within the core, there was a wedge or fan-shaped bright feature that was offset from the center, as it was trailing away from the comet. At the very heart of the comet, dead center with respect to the outer halo, lies an almost star-like nucleus, which must be the comet itself (or the last shroud of bright dust and gas that hides it from view.) A stunning sight!
