Thanks, yes I have done all of the above, I used it during the day and all I saw was darkness. I could only view anything if I lifted one of the telescope legs up and held it in place long enough to look through the eyepiece, which makes me think the lens may not be centered, but I am not sure.
I bough a Newtonian reflector a while back, after it was assembled I couldn't see anything through the eyepiece. The viewfinder works perfectly fine, but when I look through the eyepiece it is just pitch black. Any suggestions?
