It was excellent last night / this morning clearest skies I've seen here for some time. I set my scope up and pointed it at M35 took 35 x 120 second exposures, each one out of focus. When I did my initial exposure to check for focus, I didn't tighten the thumb screw which locks the drawtube, hence the weight of the camera extended it slightly, and defocussed. I'll not do that again, wanna bet!
The instruments were soon getting their covering of dew, I moved onto M101 and took further exposures to add to my previous ones.
Then finally onto M51 the Whirlpool galaxy, for some reason I didn't expect much here, but on examining the initial image it jumped and screamed at me, it looked good. So, I've produced this photograph from 41 x 120 seconds exposures. I finally closed shop at 3.30 a.m. and by this time all the instruments had a fine coating of frost.

I note that your M51 is much darker on the blog than when viewed as loaded into Photoshop from our yahoo group. My pictures have the same problem too. So I feel the need to make one version for each.
Yes, it is. I reprocessed the image shortly after putting it on the group. I like this one is better.
