Cannot focus model AP-78-9570 Bushnell Telescope
I cannot focus my model AP-78-9570. It has worked fine for a few years but now it comes close to focusing but nowhere clear enough. I only use the eyepiece at the back of the scope (the Erecting Lens), not the lenses on the sides, to view land- and ocean-based objects. Are there adjustments that can be made? Do these scopes somehow become misaligned? Any suggestions will be appreciated.

Is this your telescope?

Can you try replacing the eyepieces on the side with the one on the back. Also if you "slightly" slide the eyepiece OUT does it come to focus?
I must tell you this is a very unusual design with a turrent AND another eyepiece on the back. Has the rotary eyepiece module become loose from the back of the tube? Can you push it in closer to the tube?
Other than forward or backward adjustment that's all the focuser will do.
