Hello all, I have a C11 carbon fiber OTA that I got it with my CGE and so used it for a while and so left it in a Pacific zipper bag and left it in my garage for about 6 years not thinking of Mold & Fungus getting on the corrector plate? Stupid me!
We last week I opened it and well you guessed it, I found fungus on corrector plate on the side of the facing the mirror? What's off there is nothing on the mirror and very little on the secondary, and nothing on the facing corrector glass, this is not the model that has Starbright coatings, so I googled and found an old post talking about "Fungus on corrector plate? in the Meade listing. So I saw an great post by Dr. Clay on making your own cleaner and so I got everything on the list all but the Kodak Photoflo 200 as it's costly and I would need to wait longer than I wanted and read that Jet Dry would work?? It only needed 2 drops so why not as right now it the corrector plate was worthless in it's current condition and to replace it is about $1K.
So I mixed up the list and started. I first removed the holding ring and then removed the corrector plate but it was stuck on good so I used a needle syringe and filled it up with 99% alcohol and injected around the glass in hope to loosen the seal. Well it worked!
Also the FastStar mounting ring was loose so need to place it where it needs to be, anyone know where that notch should be at the 12 o'clock position?
So I attached 2 images a before and after pic.
So after using Dr. Clay's mixture it's 1000% better but when I fog the corrector plate with my breath please see my pic you can see the fungus has damaged or ate the coatings, but only when I fog the side that had the fungus issues. I even used 99% Alcohol and tried Photographic Solutions Eclipse Cleaning System Solution that has over 90% Methanol supposedly is 90+%. I put some on a cotton ball and spread it in an area and when it dried I fogged it and had no effect, no improvement.
So I hope if this is the best I can get it at I hope it will not be a problem unless it fogs up because of dew and plan to use a heater strip.
Does anyone have a suggestion on how I can clean it better, I have some other chemicals like hydrogen peroxide, Acetone (nail polish remover) Apple Cider Vinegar (ACV) and I read that vinegar not good for glass.
But anyone can suggest something else to try or is this the best I can get without stripping the coating off and have it recoated which I won't do, but any advice is very welcome.
