    Default Mirror Removal on Coulter Odyssey



    Hi all! First post here and I need some insight. Two days ago, my father finally relinquished his 13.1 Odyssey that he purchased 30 years ago. Iíve got a lot of work to do. He kept it stored upright in the basement with a shower cap on top, but over the years the elastic degraded and long story short, the mirror is absolutely filthy. Iíve been reading up on cleaning the mirror and I feel pretty confident in my ability to do it. Unfortunately, however, thus far I have been unable to actually remove the mirror. I removed the three screws around the bottom, but it will not budge in the slightest. Does anyone have any suggestions for removal so that I donít damage the rest of the telescope? Iím really excited to introduce stargazing to my 6 year old son, but Iím definitely perplexed right now. Thanks in advance!

    Honestly, I’m almost wondering if it is mold from being in the basement. Either way, it needs to be clean!

    That one is a toughie. I don't know exactly how to move the mirror from the cell but maybe there are some clips holding the mirror in place? If you can find these then it should be fairly straightforward to remove the mirror. I'll see if I can find anything on google.

    That looks pretty bad, it looks like the coating has been etched away so I doubt if cleaning can fix the damage. Fungus and mold can damage a mirror, they attach to dust particles and you don't want that going on for too long. You may need to have it refigured and recoated in that case, let's hope it is not necessary.

    Is your Odyssey the red tube kind? I have a 10.1" and it was a matter of unscrewing 3 bolts from the side. Of course it may be stuck after all these years but that should be it. See if you can get a thin knife in between to loosen it up.

    If your mirror is like mine it will be attached to the cell with duct tape. I realized afterwards how risky it was to keep the tube upside down as I was studying how to take it apart. The duct tape stuck well actually. I took it off, then made a new skirt of duct tape around the mirror to protect the cell from water and cleaned it that way without taking it off the cell. It worked fine.

    Okay, I found a relevant link (from here on AF.net no less) which is your exact problem. If you read through the comments on the thread you'll see how Damon was able to free up the mirror on a 13.1" Odyssey.

    Yeah, I saw that post. I’m waiting on a neighbor to bring me a six foot length of half round. I was just seeing if anyone else had any experience with it themselves. It is frustrating.
