Hi everyone,

Last Wednesday (March 23, 2010) John and I were at the “Causway” for some observing. I set up my imaging hardware and took a few photos at prime-focus of my 14.5 inch StarMaster.

Here is the result of processing M81. The image is a stack of 5 90sec images taken with my Canon 30D at ISO 1000. Actually I took twenty images, but DeepSkyStacker (the software used to stack the images) would use only 5. I don’t know why).
