Hi, I have just recently gotten a 8 inch dobsonian telescope. I have two lenses, a 9mm and a 30mm. I really enjoy going out and seeing the sky and I have a few questions to make my outings a little more successful. The way I focus the telescope is my adjusting how far out/in the eyepiece is. Whenever I have the 30mm eyepiece in, the point where it focuses is when the eyepiece is as far back as it can possibly be and its almost a little shy. Lately I have been not completely putting the lense in the eyepiece holder so that I can better focus it. So is there a reason why the focus point is as far back as possible and is there anyway to correct that? When I use the 9mm it is not like that. Also, I have been having trouble viewing and focusing some objects. For instance, last night I went out to view Saturn in the eastern sky. I located and began observing, but the object was very blurry and I couldn't hardly make anything out. Exchanging the 30mm for the 9mm only made things worse. The thing is that when I looked at the orion nebula in the top of the sky, it looked so good. Not blurry or anything. So I don't feel justified blaming it on the sky. I have read that you should leave your telescope outside for an hour to acclimate to the temperature. And I didn't do that, so perhaps that was it. Also I am doing this around lights, but I am not in direct view of the lights so maybe that could be a large effect. Sorry this is so long. If someone could tell me how to fix my 30mm focus or if that is normal, and maybe just general advice on to how to better optimize my viewing I would appreciate it. Thanks.
