Some nights everything works. Not often, unfortunately. Good seeing
has been very hard to come by this winter but finally the seeing gods smiled on me and I had good transparency as well. I had time to process this as we are finally getting our first snow of the year that was more than a dusting. We should have 75 cm or more on the ground about now. Until today we had less than 1. Now we are up to 10 and it is still coming down, slowly but that's better than nothing. Not much but sorely needed. Unfortunately it is a pretty dry snow. Still, I'll take the clouds for that! Anyway, look around, there are lots of interesting small faint fuzzies in the field. 14" LX200R@f/10, L=9x5' RGB=3x5' all binned 2x2, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com.

Nice image Rick. It looks a bit dark with some green missing to me...but my
monitor is and old CRT so that may be what the problem is also. I checked the brightness range and I can't differentiate the 2 darkest zones anymore. P.S. Are You in MN and if so what part?

I reprocessed the image for my monitor and I have to say that the number of
back ground galaxies is amazing...WOW! I took a shot of M97 last year and there is a bunch of distant fuzzys in that also. Joe "Rick Johnson" wrote in message ... Some nights everything works.

The green does seem a bit down to me too but when I put it up the
background went really green and much of the galaxy tuned a funny blue green color. Problem is that my STL-11000 is one of the very first ones out and has no heaters around it's optical window. They are coming. With the extreme cold (below 30C) that was taken at I get a faint frost on the front of the optical window. It plays havoc with the color. It is also so uneven (changes each frame) that there's no use leaving some grey in the image as the frost hides any faint detail you'd otherwise see. I also found a red light leak in the 4 port Sidewinder that was easily fixed once I realized where it was coming from, an opaque red port cap wasn't quite opaque! Also I have to drop the background darker than I'd like to get rid of the rainbows of color you'd otherwise see from the frost and that faulty cap. Temps are now 20C warmer now so the frost problem shouldn't be there any more but it is also cloudy so I can't test anything as yet. When the heaters arrive I'll put them in as well. I'm on (Big) Mantrap Lake at 47.08122N 94.91494W per a borrowed GPS unit. The scope is about 60 feet above the lake and 16 above the ground level The Google Earth image was taken before we built (though dated later) so there's nothing in the picture but forest and a hint of the drive we cut the year before building. Many of those trees kept us warm the last two winters and have enough for yet another winter. Kept us warm cutting and splitting it too! Rick J McBride wrote: Nice image Rick.

Sounds like your monitor is a lot darker than mine. I do have all in
the dark end but missing one in the white as this 5 year old LCD is showing its age by dimming on me. I use a different one for processing that does show all levels. Yes M97 has a bunch, being near by that isn't surprising. I took a shot of it at the same time as 108 and will post it when I get it processed. The shot with my 6" f/4 I took last spring sure showed a bunch. It has a somewhat larger FOV so won't pick up as many with the 14" and at f/10 doubt it will go quite as deep either. Actually I took M97 before 108 and if I remember right the frost hadn't yet developed to the extent it had in the 108 shot. Will find out when I process it. I'm still about 5 or 6 shots behind in my processing. Dealing with the frost issue just doesn't make processing any fun! Then we ended up getting about 17 cm of snow. More than than twice what we got all season. I have a km of drive to blow clear. Waiting for the wind to settle down. Its a very light snow and will just blow back in my face. Right now I'm working on another shot I took the same night (it was an all nighter due to the good seeing). Frost is giving me fits but I think, if you ignore the varying color balance due to the frost streaks on the window it will be a pretty good Leo I.

Dang, I didn't know you are in MN? I am from MN to, grew up in North St.Paul and Minneapolis in
Blaine City in Anoka County off of 35W. I love the Twins and to watch them play ball in the dome. Was there for the W.S.1987... Which in 2010 they should have there own stadium... Best dark sky I ever seen was in way upper North East MN on the border of Canada and USA. In portage country which we were doing. Nothing has compared to that sky... Mantrap Lake near Park Rapids, MN... how's the light pollution there? Got any light domes? I miss MN, but not shoveling the white ****! Loved to play in the snow. Anyone here in SC says it's cold. There full of crap! I know what cold is!.. your location? http://tinyurl.com/yr8lvg |

There full of crap! I know what cold is!.. your location? http://tinyurl.com/yr8lvg Yep, that's where the observatory is. House is to the west. At the time that was taken the power line went right through where the observatory was built and through the kitchen of the house as well. They had to move it at their expense as the county told me this was where I had to put the house. Would have made a place to hang the dish towels I suppose. Just to be grounded when you hang up a wet one! Minnehopeless (they seem to have the gang killing of the day of late) runs a lot warmer than we do. Though they get more snow as well. We run a good 20 degrees colder up here in winter. They scream at -20. The screaming here starts about -40. Park Rapids is a very bright dot on the famous light pollution photo of the US. For only 3000 folks it is as bright as many four and 5 times its size. They sure know how to waste electricity lighting up bird bottoms. Fortunately it is almost 20 miles away and not much of a problem. About the same size dome as Bemidji which also is way brighter than it's 11,000 population should be. Must be all those signs to entice you into the tourist traps. Though most are down for the winter their signs never go dark unfortunately. Bemidji is to my north where trees block the view so no problem. Most of the sky has a limit of about 6.5. Neither dome goes higher than 15 degrees and below that my seeing is so lousy I rarely image there anyway. While I've been in the boundary area and know its dark skies they don't begin to compare to the sand hills of Nebraska. That's because the humidity and dust there is so low. They have less sky glow as well. The boundary waters have no artificial light but the sky glow there, and here is a lot worse than in Nebraska. Also they are humid with all the water and there's more dust than in the sand hills. The boundary waters are really no darker than here just without the two light domes on the horizon. I still had the same 6.5 limiting magnitude when there. In the sand hills I can easily see down to beyond 7th magnitude. Some claim 8th but I can't do that, maybe 40 years ago but not any more. The Milky Way casts a very obvious shadow. That I can see. The club in Lincoln I helped found in 1961 along with two others in the state hosts the Nebraska Star Party out there each year. Its a family star party with lots of activities for the rest of the family as well. Now that's a dark sky! http://www.nebraskastarparty.org/ Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

Rick,
certainly one of the best M108's I have seen. Seeing your image I recognized a spiral structure in M108 for the first time, I always thought it was too much "edge on" to see the spiral.

I'd love to know what it looked like face on. Still looks "troubled" to
me. But it does appear one dust lane does go almost half way around from the "front" to part way down the "back" side. My M82 shot seemed to show a bit of that as well. I'd never noticed in in either before. Kind of fun when you see something in your own shot you never noticed before. Probably happens because I do look at mine more closely than even the big observatory or Hubble shots. Rick Stefan Lilge wrote: Rick, certainly one of the best M108's I have seen.
