M51-Whirlpool Galaxy on 8/10/08

Tonight I spent almost an hour refining my alignment using the DSI camera and the drift alignment technique. In the end, I think I’ve pretty much figured it out and I wound up with the images only limited by periodic error which I’ll (hopefully) work on correcting over then next couple weeks.

As a result of the successful alignment, I was able to take lots of 1 minute images with minimal star trailing. I decided to have a go at M51 – the Whirlpool Galaxy to see how well it was working. It was working very, very well. I was able to gather a bunch of images which were stacked to make the image above. Since the Moon was really washing out the sky, I thought the end result was really pretty good. I’m excited about finally figuring out drift alignment – I believe that’ll wind up making a big difference to my future imaging.
