It's been a while since I did a blog, so after twiddling the way the front page of the site displays, it's time to post a new one. The attached photo is of my favourite dark nebula, "The Dark Doodad". What looks like a long thin nebula is apparently a sheet over 40 light years wide that we happen to be seeing edge-on. On the left you can see a few dark tendrils that are par of the coal sack nebula. This is one of the first images created from a stack of subs I took using AstroDSLR. Each exposure is 2 minutes and I stacked 20 of them. My polar alignment was pretty decent, I think!
