I got up early and went over to the VFW parking lot. I got in little actual viewing, but it was still fun.

As soon as I got out of the truck I could see a fairly bright satellite moving west to east high in the north. I just now checked Satellite Safari and no, it wasn't the ISS.

First, I realized I had forgotten to scope out lights in the parking lot. There's a bright dual sodium vapor light set where I planned to set up. But in their lower lot the light was turned off and I found a place where some decorative evergreens blocked the glare from the first. None the less, it's an overall fairly bright area, illuminated by other lights in the near distance.

It only took a couple of minutes to set up. I decided to start with Jupiter. Seeing was superb. The problem was that a thin layer of frost soon started forming on my EP. That was a problem I wasn't equipped to deal with. I used pretty much all of my EPs for a couple of minutes each, but no joy. At some point I looked up and realized it was brightening in the east.

Anyway, as I say, it was fun. I'd do it there again, possibly in early Dec. with the goal of comet spotting.

with only an hour of 2 minute sub exposures and a third of them taking punishment from the moon, I'm not too disapointed in my m33 from last night..

I am (disappointed). What is that? Did someone sneeze on your objective?

Just kidding. Jealous really. I went out last night to check conditions and had a haze/fog around my house. Not worth braving the cold for that. Of course at bedtime (12:30AM) a substantial improvement. But I'm old and tired.

You wouldn't be so tired if you went to bed at a decent hour, Stacy. But you'd still be old.

Pretty cool, Robert! If M33 was at 12:00 for you, what direction was the moon? With the seeing so good this might be a good time to try Jupiter or Luna.

Does anyone know of a good spot south of Seattle that is dark enough for AP?
Rattlesnake lake has horrible seeing most of the time and I am looking for alternate locations.

Sorry Andy, I've never ventured that direction for imaging. I've never found anything on this side of the passes that really stands out due to the marine air from the Pacific.

Thursday night was pretty good out here. I setup my Quantix and spent the whole night with the OIII filter.

I combined the OIII with some Ha for a bicolor of M42 but didn't have any short exposures to tame the core. Solution: I dug up the LRGB I shot last year with the Quantix...

Nice Orion!
I ended up going to the Yakima Canyon. I compared my subs from Rattlesnake Lake and from Yakima and there is a dramatic difference in sharpness. I think for small targets Rattlesnake Lake is just a waste of time for luminance. For RGB data it should be OK tho.

Thank You Stacy, Mike and Andy.

Thats what I mean, Andy. Sometimes the conditions come together and imaging on the west side can be good, but most of the time...not great. The East side has better conditions due to dryer air. It may not always be great in all aspects, but that reduction in moisture go's a long way to reduce the impacts of other factors.

Where in Yakima Canyon do you go?

I usually go to the Lmuma Creek recreation area. Its protected form the headlights of passing traffic and it has a fairly open horizon.

The last time i set up there with my scope, i was amused by the educational signs there that were contrasting the daytime canyon wildlife with nighttime wildlife -- they could've added a section on human-life as well. The daytime human-life (fishermen) were just leaving and the nighttime human-life (starwatchers) were just showing up.

The sky exposure was fairly good, but i remember it being pretty cold though. This was February, i think. I like my comforts, and i've really got to come up with some better arrangement next time i go there. Maybe i need to buy a tent and air-mattress, or something. Or maybe a big fancy motorhome with a 40" flat-panel TV that i can hook the telescope too...

Yes I was there on Saturday night and it was about 18F. The seeing was excellent and there was no dew at all. I usually nap in my truck, I have a sleeping bag that is rated for -20 and it works.
I was only able to get about 6 hours of Luminance on my target but it's a start.
Here is what I have so far.

I think I should have framed it better to feature the galaxy group at the bottom right corner but I had no idea that it was part of my shot!

But very nice! I lost count of the number of galaxies in that shot. Got to be at least 30-40, i'd think. What part of the sky is that in? Is that M104? I suppose i should know, but i've taken the last several months off starwatching to rest my back and i'm a little rusty now.

Oh, okay. I was thinking it really looked too edge-on for M104. Now about 25% away at 4:45, is a tiny deranged face-on galaxy that has the bottom arm stretched out like it's interacting with something. Might that be an ARP galaxy? Any guesses as to what galaxy it is?

I was wondering the same thing. Astrometry.net did not tag it. I need to do a little more research on that. I think I need at least another 6~8 hours of L and same amount of RGB to really make the detail pop.

Okay, a quick check of my copy of "The Great Atlas Of The Sky", and then some googling says that it might be PGC 9101, whatever that is. An obscure galaxy i can't find much info about. One google hit states:
Quote:

CGCG 538-059/PGC 9101 is one Arp missed for his category spiral galaxies with a low surface brightness galaxy on an arm. Like many Arp put in this category, the companion has no red shift data. In this case the field is very poorly cataloged so it isn't even listed. While it appears likely it is a true companion I can't verify it. It is a very blue galaxy that could indicate interaction. The main galaxy has one cut off arm and one long one apparently drawn out by the companion.
