There are three screws with springs around the mirror and I do not know where that mirror is suppose to be screwed on inside the telescope.

The three holes in the bottom plate should line up with those three screws or "studs" and there should be some kind of "hollow nuts" possibly that thread on the studs, once through the holes. Is there more parts? Link to comment Share on other sites More sharing options...
NGC 1502 Posted July 24, 2019 Share Posted July 24, 2019 Hi Angie. Folks on here are happy to help, but a few more details would let us give advice. You say that the mirror is “completely off”. Do you mean the mirror needs adjusting ( collimation ) or has it been removed from the telescope tube by dismantling ? Ed. Link to comment Share on other sites More sharing options...
Ricochet Posted July 24, 2019 Share Posted July 24, 2019 I think photos would help in this situation. "Completely off" sounds like either the secondary stalk has become unscrewed from the spider or the mirror has fallen off the stalk. Link to comment Share on other sites More sharing options...
Ruud Posted July 24, 2019 Share Posted July 24, 2019 (edited) The pictures show the problem well. I hope you have the three knobs that are needed to hold the mirror cell in place. Together with the screws that are still in place, you use them to adjust the tilt of the mirror. Check Youtube to learn how to collimate the optics. Here's one of the many instruction videos on the topic: Edited July 24, 2019 by Ruud Link to comment Share on other sites More sharing options...
Swoop1 Posted July 24, 2019 Share Posted July 24, 2019 Hi Angie, Your telescope is missing 3 adjustment knobs. The back of the mirror has three threaded studs which have the springs around them (visible in your picture). These studs protrude hrough the holes and the knobs do up over them. Adjusting the knobs collimates (lines up the mirrors) your scope. The back of my scope is shown below as an indication. Mine isn't the same make but it is the same concept- a Newtonian telescope.

Tomatobro Posted July 24, 2019 Share Posted July 24, 2019 (edited) I think that what Angie is saying is that the collimation screws with the springs have become completes unscrewed with the result that the mirror cell is loose. The best solution is to find out where your nearest Astronomy Club meets and contact them. I am sure that a member will come to your rescue and show you how to fix it. Otherwise the cell has to be removed and the screws reconnected and then the scope will need to be collimated. I am guessing that you have the three screws that came away?
