You are so kind. Thank you. I don’t know if I understand all the lingo. I just don’t understand why they won’t screw in, 3 of the inner ones will but others just seem to just push the back of the ota forward rather than screw into it. Oops I ended up merging 2 and 3 but forgot to fix the numbering. I guess at this point if that baffle is off I wonder if it’s better to just try and buy a new scope. So much work for this one and I don’t even know if it’ll even work 🤨 thank you again!

I am excited to join this big star gazing community! I realize I am abusing of your kindness, so that you in advance for any help you can give. I have an old telescope, what appears to be a Meade ETX 90 from the early 2000s. I cleaned it pretty well after many Youtube videos and online research. I found full blown spider webs and dead spiders! I have encountered a few of issues as I'm putting it back together and I wonder if anyone might be able to help. 1. I took off the screws of the back of my OTA (I know I shouldn't have!) and now I'm not sure how to put them back on (see attachments). When I try it seems to push the primary mirror instead of fastening to anything. 2. My secondary mirror flip is broken, the plastic piece part fell off. Is it possible to fix? The mirror itself is also very dirty (see attachments) and I don't think it can be cleaned further. Any tips on how to replace it and where to buy the parts? Or is it possible to not use the 90 eye piece viewport and instead use the front one so I don't need to fix the flip or the mirror? 4. My secondary baffle is sliding off. I've read that this is a problem w/older models. I tried pushing it to the right place and it requires some force, but after 1 minute it slides back to its original place. What should I do? Does this matter? 5. The plastic attachment to hold the smaller lens (finderscope?) wobbles no matter how tightly I screw it on. I don't know if it has anything to do with the front plastic part being a little broken. Thank you for your help in advance, and I am still learning terminology so be easy on me
