Challenge: Best of 2007 (Advanced Editing VII*)
Camera: Canon EOS-350D Rebel XT

Aperture: 160mm

This is a composite of 10 4 minute exposures of the andromeda galaxy. Located 2.3 million light years away from our home galaxy (the milky way), this galaxy is the only consistently visible object in the night time sky that's not part of our galaxy. This shot was taken this past September, Canon 350xt, ISO800, tracked with a Losmandy G11 mount, lens was a Tak e-160 telescope.

Processing: each of the individual sub exposures needs to be aligned to a single master, as there is a tiny amount of movement from subexposure to subexposure, if you didn’t do this, the end product would show stars as arcs. I used registar to align the subexposures, then brought all 10 into ps7, layered all 10 and set the transparency for each sub in descending order, the first is 100%, second is 50%, third is 33%, fourth is 25%, etc… for each individual sub exposure I did color correction pulling down the red midtones and bumping up the blue and greens, selective contrast enhancement and finally selective curves. Flatten image and repeat selective contrast enhancements and curves.

Have you ever heard of Alex Collier? he claims to be from there! What a great shot, and this galaxy looks rounder than ours.

This is such a cool shot. I could venture a guess...maybe 900-1000 sec?! You have great color and framing here. It makes me think of the DVD Louie Giglio produced that is called "How Great Is Our God". I like this alot -BB

P.S. Is this ' . substr('//www.dpchallenge.com/images/user_icon/21.gif', strrpos('//www.dpchallenge.com/images/user_icon/21.gif', '/') + 1) . ' jlanoue?

I have passed over this image a few times now and although I really like astronomy, this really does nothing for me. Sorry. Good Luck. 4.

Quite an impressive "Best of" :)
I bet it's even better at full resolution.

The purple hue lends to femininity, making it more sisterly.

Wow! What an amazig capture. I have tried so hard (unsuccessfully)to capture a sky full of stars like that. I am incredibly impressed, and will definitely be going back after the challenge to see what settings you used, and to see if you gave any tips on how to accomplish something this stunning! Hopefully this will be in the top few so it will be easy to find :)

I didn't realize the Hubble telescope had sold. One hell of a telephoto lens is all I can say...

Lovely view indeed. I look forward to reading more about how your photo was taken when the challenge ends. 8.

Ah, my favourite galaxy :)

Beautiful image. I wonder if a bit more post-processing could have made it pop even more though?
