Losmandy rings for Celestron 80ED.....

How are you all doing,
Does anybody have a suggestion for the correct size rings to buy for the Celestron 80ED........108 or 125mm?


Thanks,
Mark

Hi, I think the Losmandy 90mm rings would work for you..just make sure that the front of the scope can fit through (like dew shields).

I'll make note of that too! I'm getting my 80ED on tuesday

Keith..

90mm sounds a bit tight imho. wait for the tube to arrive first and then measure the ota diameter. better to get slightly larger rings now which may deal with a larger ota in the future than cutting things too tight now.

Thanks for the replies. I think the 90mm rings might be a a non-runner. The widest part of the tube(dew shield) is 105mm and I think even the 108mm might still be tight. I'm thinking along the lines of the 125mm rings. I'm presuming the screws screw down 20mm???

Also, I would recommend telescope-service.com in Germany. I ordered some kit last saturday and received the kit on thursday. The price was alot cheaper
than equivalent in Dublin.

Howdy,

I'd go with the 125s. I'm using that size for my 70mm refractor and there is still plenty of play left in them.
Their not the Losmandy's though but I guess it would be similar.

Incidentally, since you haven't ordered yet these are the rails I'm using. Much cheaper than Losmandy but I imagine they wouldn't be as well engineered. They work well though. £90 or the rail and rings!
