Help My telescope fell and now it won't focus

[danielandpenn]

It fell halfway over, denting my metal garbage can lid. The finderscope came off but I could easily reattach it. I can see light and blur now...what should I do?? I don't want to just open it up without knowing what I'm looking for. Thank you!

What's the model number?

General suggestion: Try checking the collimation.

Sounds like a reflector which fell 'headfirst', suggesting the seconday mirror mount is now misaligned. Assuming it has a spider mount, loosen and retension the mounting screws until it recenters. You can do this in daylight using a distant object to roughly recenter the focal plane, then a bright star at night to fine tune it.

What type of telescope is it, Refractor, Newtonian or Catadioptric ?

The model number is 78-8840

Thanks so much everyone. It is a Mak Cassegrain by Bushnell. I will try your advice, first, Chronos. Thank you.

I got it! I unscrewed it, opened it up and put it all back and Voila! It's perfect! Thanks!
