Well my new 10" dob is out of the box 4 weeks early and there have been very few clear nights. I must admit to wondering how one ever feels confident about collimation results, I've read endless articles from the web. I haven't a clue whether it's right or not. I'm also just a bit dissapointed with the views. I have pretty dark skies and was looking forward to find a galaxy or 2. I finally found the sombrero (M104) but it was just an angular smudge with a lighter smudge in the middle. I guess all the talk about seeing structure in galaxies with a 10" led me to certain expectations. It all looks so sharp through my 20 x 80 binos or through the finder, but at 40x in the telescope it's all a bit dull. hmmmmm
