My first DSO. 47 Tucanae. You might see a lot of globs from me (kind of a glob nut). This is my very first astro image taken with my Canon 40D. It's also my very first deep sky shot, so please be gentle. Scope wasn't perfectly collimated and /or the FR has some issues. Not quite 100% focused maybe...
8" SCT @ f/6.3. Canon 40D. ISO400, 1 x 20sec. Dark frame subracted. Tone curve adjustment in Canon DPP.
That is a pretty good first up attempt.
You may like to try and take a few more images and stack them. I have been using Deep Sky Stacker. It is pretty easy to use and seems to work for me.
For a first effort you have done well, and as with what the other guys said take a few more and stack em, and you will be surprised at the detail that will come out.
I actually did use Deep Sky Tracker to stack some. As you can see there are some registration errors. However, since I took these shots in Alt-Az mode, I'm pretty happy with the way they turned out.
Reprocessed with DeepSkyStacker. I was a bit more savage with the rejection rate. This is a stack of 3 images plus dark subtraction. Some chrominance noise reduction plus tone curve adjustment.
