Gotcha, it helped a lot to open the bottom bit and take a look inside, apparently old telescopes are a great decapitated wasp storage device... So replaced the screw and made sure the tube is nice and tight. It stopped wobbling and seemed to be much better. I had some random screws that fit the nut I found and were not too long.

Now for the next job is how to make sure I can see anything at all through the eye piece? I am using the 20mm one, pointed the finder at the moon, but the eye piece sees nothing.

If I remove the eye piece, I can see my eye and the mirrors look close enough to the middle, but I guess they are not aligned enough if I am not seeing anything through the eye piece? (Gonna wait for daylight tomorrow to try to focus a far away electricity pole). I also tried shining a light into the front of the telescope and I can see that blob through the eye piece.

So I am guessing its either misaligned mirrors or maybe misaligned finder? Il check during daylight tomorrow.

Any advice on a tool I can use for aligning it? From what I read I need a Cheshire eyepiece? But are there any beginner friendly models that are not too expensive?

Also the finder seems to not be in much focus no matter what I do it it, the moon ranged from a complete blur to semi-blur...
