i agree but my wife doesn't see it that way... i do alot of diving in my spare time so she relates the cost without knowing anything about the sky life.....

I doubt a recoat is necessary. Maybe a cleaning. I recently cleaned up a 1957 Cave mirror with the original coating and it is still pretty good. The Meade coatings were excellent. I'd consider a cleaning first, unless you have obvious grey corrosion areas on it. GW

A good cheap 1.25 eyepiece for this is the 26mm Meade series 4000 Plossl. They are everywhere, because they came with a lot of scopes. Actually, the whole series 4000 is good and available for very little.

A good low cost 2" eyepiece is the 32mm Meade series 5000. It would cost a little more but it's worth it. I could make do with just the 32mm 5000 and the 9.7mm 4000 if I had to. Seems like I did for a while, in fact! GW

i spoke with hands on optics and was told that due to it sitting around the coating oxidizes about 1% to 1.5% each year so a 10" over that long of time has deminished to roughly an 8" in terms of light gathering capability and clearity

mmmmm..... maybe..... maybe not! I would clean it and use it. When I let go of mine two years ago, the coatings were still eye-hurting shiny. A 1997 model. GW

Ronaldbrownjr, please go out and look through that scope. They were pretty good when they were made and many are still giving good images on the original coatings. From your remarks it seems that you are anticipating problems and I don't think that is warranted. Try it out and after using it a while, decide if any work/recoating/new parts are warranted. I used a Starfinder 10" as a dob for three years and now acquired the ridiculously big mount. The Starfinder OTA provided me with good views and the focuser was adequate but not great. If I singled out the most annoying thing on it, it would be that secondary adjustment is mechanically not very good. But that is really it for my complaint list. Run out and point that thing at the sky.

Regards,
Brad

Edited my typing/spelling.

I agree, it is as close to a Dob as you can get on a EQ mount. It is so basic and will last forever, except maybe the clock drive. GW

If the mirror looks good don't touch it. The part about the mirrors degrading is not completely true. My 93 mirror is still like factory new because it was cared for and stored properly. Others that have been abused may be junk.

It seems to also depend on climate. I have spent my time mostly in drier areas of Texas and have seen coatings stay nice for many, many years.
