I don't know much about lenses and stuff so i'd appreciate all the help i could get. I understand a solar telescope is way out of my price range but yeah.
Also, i was wondering if it would ever be possible to take a picture with a telescope? I know that's a weird question but yeah.

Thank you all in advance,
Dale

Being on the roof would eliminate the problem of trees being in my field of view.

please

thank you!!!

I use a 9mm eyepiece most of the time. I am also have a 10mm, 26mm, and some more around that size. I have located the Orion nebulae, can you list some more messier objects that I can see with this telescope. I live in Ontario California so I have light pollution but not like big cities. I live in a little town.
