I have a telescope that I received from a teacher. I know it's a celestron but I can't find any info on the model/type, and I can't find the name of the telescope anywhere on it. Can you tell me what type of it and if I need the electrical parts to make if work? Here's a link to a photo of it. https://photos.app.goo.gl/ZtBm1pe1fTszG9FQ8 I don't have a manual for it as I don't know the model so I can't figure out how and what I need to fix it, or make it work(if it's missing a specific piece or something) I need to know what model it is so I can find the pieces for it and learn what it needs to work.
