Wow!!! Thanks guys.....it's tough to make a choice...seeing I've been weather/Rain bound for two months....I'll get out the "The Sky" and see what's up there for Feb.

I checked out the sky and I think the M81/M82 combo would be a very nice target. It's also a favorite of almost everyone. Now, with some of the instruments, this wide field of view might not be possible without a mosaic, and in that case I'd say just M81.....I'll leave this decision to the moderators.....of course, we could give extra credit to those that do a mosaic for the widefield..

Congratulations Bud, that is a great shot of M42 (I voted for it).

M81/M82 sounds like good choice (although I kindof like the lesser known objects).

nexstar 8 GPS, IDAS LPR filter, f/6.3 FR, SXV H9C
2 nights of 30 second subs, 1 night of 60 second subs
after throwing out subs ruined by passing clouds or bad tracking wound up with about 2 hours of 1 minute subs and 2 hours of 30 sec subs.

thanks folks
i'd especially like to thank gary, jim, paul and david for not entering their images
i think gary's would have had my vote

come on folks let's pony up for M81/82
that's a tough one for me as the camera won't clear my fork mount for the shot, so i'll have to resort to hyperstar with the camera in the front.

as for march i'm torn between the leo triplets
or ngc 2903, or NGC 3628 solo

well triples are too hard for me until i get my refractor up and running. i've wanted to do NGC 2903 since reading last year's small wonders: leo article
http://www.cloudynights.com/item.php?item_id=497
but overall i think pale in comparison to M 81 which we're doing now.

NGC 3628 is so bizarre looking that i think it deserves a solo shot.

so its NGC 3628

NGC 6791 by Hoser (June 2006)

Taken: 6/16/2006 and 6/21/2006

Conditions: Transparency very poor, seeing about 5" (very poor night...but the first opportunity to image in weeks due to rain, so I coudn't resist.)

Equipment:
- TOA-150
- Paramount ME
- SBIG ST-2000XM, self-guided
- ST CFW-10, Astrodon LRGB filters
- FLI PDF

Exposures: (170 minutes so far)
- L = 9x2mins + 8x3mins (42mins)
- R = 10x2mins + 8x3mins (44mins)
- G = 9x2mins + 8x3mins (42mins)
- B = 9x2mins + 8x3mins (42mins)

Processing:
CCDStack:
- initial sub registration
- RGB combine, used to generate synthetic luminance (Ls)
- Ls mean combined with the natural L
- DDP

Registar:
- LsLRGB combine (yes...Registar did a better job at this step!)

PSCS2:
- gradient control
- noise control (NeatImage)
- slightly increased hue and saturation (Interestingly enough, I did NO increased saturation on the bright orange star in the upper left!)
- curves to bring up the mid-tones

M63 by Chuck Anstey (Mar 2007)

M63 shot over two nights March 11th and March 12th, 2007. Skies were below average transparency and straight at Atlanta, GA light dome so LP was high. The noise per sub-frame exposure was 45-50 ADU RMS so I figured I needed between 50 and 60 frames to drive the noise down to the correct level. I was able to simply let the AP1200 image unattended all night long so I got 68 frames.

Equipment:
Telescope: Celestron C11 + Focal Reducer
Mount : AP1200
Camera: SBIG ST-10XE + CFW8a + Astrodon Tru-Balance LRGB filters.

Conditions:
Transparency : Below average
Seeing : Between 2.6 and 2.1 FWHM (4.0 to 3.1 HFD) over the course of the night.

Exposures:
L: 6 minutes x 66 frames (rejected two)
R: 6 minutes (2x2) x 9 frames
G: 6 minutes (2x2) x 9 frames
B: 6 mintues (2x2) x 8 frames (rejected one)

I had an additional 6 RGB frames each but they did not improve the color image when I added them.

Processing:
CCDSoft: Dark, Flat, Align
CCDStack: Stack and create color frame
CCDSharp: Lucy-Richardson deconvolution on Luminance
Photoshop CS2 : Image processing and LRGB combine

This was taken on the night of January 7th from Chiefland Astronomy Village in Chiefland, Florida. Imaging at 29 degrees of latitude N was a real help on this image.

RGB 70-70-120m using 10m subs. TV-76 with 0.8x reducer, SBIG ST-2000 with CFW-8 and Astrodon filters, EM-200 mount. 5 sec guide exposures using the ST-2000 guide chip. Calibrated, aligned and sigma reject combined in Maxim. RGB channels merged and processed in PSCS.

Camera was my SBIG ST-2000XM and CFW-9 with Astronomik-Filters.

April 2011 (NGC 4490) by darkforce:

"before I had all the Adapters, which are necessary to attach the extender to the FSQ, I decided to give the small focal length a try at a very small GX, called NGC4490 . So, this is not a high resolution closeup @F5 with 530mm focal length, but I hope, to comfort in the tons of background GX you can find in this image. "Chara" is very, very bright and it was a big challenge, for the image processing (gradients etc.). The seeing condition were very nice, so all my 600s RAWS had FWHM's-between 1,8" and 2,0"."

May 2011 (IC 1396) by Paramount:

It was taken with a Takahashi FSQ106ED at f5 on a Paramount ME with a Starlight Xpress SXVF H9 and 5nm narrow band filters
Exposures are 8x30 minutes for Ha and 10x30 minutes each for OIII and SII
Auto guiding was done by a lodestar and OAG combination
After calibration the master frames were colour combined in Maxim DL and the processing in Photoshop consisted of a couple of iterations of levels followed by several small contrast curves adjustments, finally the colour was balanced using selective colour. No sharpening or noise reduction was used in the processing

June 2013 Challenge (NGC6946) by Tyler Allred:

Here is my entry for the June challenge. It was taken with my homemade 12.5" Zambuto astrograph, dubbed the "Supernova Astrograph". I spent four nights on this target, but one night had terrible seeing... so bad that I decided not to use the data at all. The night I collected the color data wasn't a great night either, but much better. The luminance data was a different story. I finally have the collimation of my scope nearly perfect, and I got two great nights with stable skies, which is unusual here in Utah. We always seem to have the jetstream right over our heads and the seeing is frequently quite bad. At any rate, I combined the decent color data with really good luminance for this image. I have attached a 67% reduced crop, but the full version is worth a look as well.
