Another rough shot on the night I got my telescope back from repairs.
13x 30 second exposures, 6.5 minutes total exposure time. ... Obviously could have centered it better to avoid the field curvature.
M57 is a planetary nebula ... a shell of gass puffed off of a star similar to our star but near the end of it's life. A last hoorah before fading out as a white dwarf.
First light for my new ATIK 320E!!! I just received it today, and of course Mother Nature threw her best at me - but I was NOT to be denied (I vowed to shoot the neighboring town's water tower if I had to!) There were puffy clouds going over all night (about 40% cloud cover) together with constant 20mph gusting winds (every 20 or so sec) - not very good conditions for long exposure work.
This caused me to have to reduce my subs...to a ridiculously short 3 seconds each. Yea it's crazy but I took Lum=100x3s, R=50x3s, G=50x3s, and B=50x3. then I threw out all the subs affected by the wind gusts and clouds, which turned out to be about 25% of them. leaving a total of 9min 22s of data split among LRGB channels. Don't get me wrong, this image is nothing to write home about, I know, but for 9min of data using 3s subs, I'm pretty happy with how well the new setup performed. I'm com'n from a Meade DSI2pro and the ATIK320E was completely free of warm/hot pixels, even at 90s subs (which I started out trying to get, but it was completely useless with the wind!) I suppose most of you have decent camera's and are used to this low level of noise, but I am currently amazed at it! Also, if the wind had not been around, I could've taken longer subs and used Ha filter to keep the stars tighter/smaller.
As it was the first night of DSO work with my new equipment, a few items popped up which need some work. First off, my finder scope that I'm going to use as my guidescope came loose as one of the screws stripped out...bummer. Next, I found some slight coma in my image, which i'll have to work out by adjusting the spacing between the scope, f/3.3 reducer, and camera - although this may be difficult as I'm trying to squeeze in a filter wheel. Also a bit of a bug is that despite processing the R, G, and B data exactly the same, somehow the image here has a green cast...is that an expected result (light pollution)? all the images I find online show the core and inner part of the ring as blue, fading to yellow then finally red on the outer part of the ring. Anyhow, I've never done LRGB with DSO targets before, so I'm sure I have some learning ahead of me. If anyone has some advice for getting good color balance, I'd love some help!

Hi Dave, This one I "didn't" apply the Noel Carboni light polution removal tool. I think it's better??????? I also made some flats and cropped it.

An animation showing the motion of dwarf planet Ceres and minor planet Vesta against the background stars, over 3 consecutive nights. The bright blue star near the top of the frame is Eta Virginis.
Each frame of this animation is an image obtained by stacking 10x2 sec exposures (taken with my Canon 50D and Tamron 90mm macro lens at f/2.8 and 1600 iso) using DeepSkyStacker.
Using a 6" f/5 Newtonian reflector with a robotic mount. Twenty exposures (15s each; ISO 3200) on my Canon 50D in the direct focus of the telescope, shot using electronic shutter (FRSP) + intervalometer features of Magic Lantern firmware. Assembled using DeepSkyStacker software. Faintest stars on this photo have a magnitude 16.2m (factor of 3 fainter than planet Pluto).

4 x 600 second subs
Taken at Byng Inlet, ON.
Second night out at Byng Inlet with the ZEQ25. Dew was a real issue last night as it started to set in around 11pm and the small Goal Zero battery box I brought doesn't last long enough for a full night of imaging with the mount, camera and laptop plugged into it. So I just shot one target tonight.
The ZEQ25 and StarShoot Auto Guider seem to work really well together. I was able to take 10+ minute subs with minimal trailing. As the battery was depleted the mount started to struggle to track so there is some star trails in the last 600 second exposure that is in this stack.
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. It is sometimes incorrectly called the "North American Nebula"

Andromeda 1/30/2015 – 9:06:13 PM, first ever attempt at photographing, first time seeing, 2 mins 30 sec elapsed time, deep sky stacker, PS 5.5, Canon 50D, Tamrom 70-200 at 200mm, tripod self guided, ISO 1600, 1 sec, f2.8. Personal note: Kinda proud of myself. I actually captured a rudimentary image of the Andromeda M31 Galaxy. This is a total exposure time of 2.5 mins. Amazed that I was able to get this with a 200mm lens. I couldn't see Andromeda but was able to find it through the camera. This is actually the first time that I have knowingly seen this wonder with my own eyes. There is another galaxy slightly to the right, M110. By the time I was finished there was frost on the camera.What is even more surprising is the dust lanes are visible. No crop.

First test of my new Astronomik Hydrogen Alpha filter on the Horsehead nebula.
I am so happy with the consistent results I am getting out of the G11 + Orion Starshoot autoguider combo. Now that I am getting used to the mount, setting up is very quick and once guiding is set I can leave it taking 10 minute integrations and just forget about it while it is doing its thing.
