Mark you just need to measure the diameter of the glass at the bottom of the eyepiece holder. As long as you pick an eyepiece shorter than 20mm focal length in the 1.25" barrel size you should not have much vigetting if any.

saw an adapter other day that allows you to use zeiss ep in standard fitting scopes, ie converts it to a 1.25" ep. for the meagre price of $170! I wont be rushing to buy that!

I doubt zeiss ep surpass other genrally available astro eps?(lanthanum lvl eps i mean) Unless the zoom has a particularly widefield?

A 2" astro eyepiece is BIG.
Think about it 2" = 50mm, so the fitting is the size of biggish binocular objectives. Then the EP body is bigger still.

I have one for a WO Megrez 90.

If you are thinking of astro EP's stick to 1.25 ones, there is a big range of them.

I have the same scope and wondered if the Baader zoom could be made to work on it.

AFAIK Kowa never made an astro adapter for it.

THis site has some info which shows one way of adapting some takahashi eyepieces to an 823 kowa. Need to translate from French to English though.

interesting, that adapter looks like the one which allows you to use the kowa screw thread eyepieces on the bayonet mount, but i doubt its the same 1.

From Birdnet Optics I believe it is the "Adapter to fit 66 Series eyepieces to 82 Series Scopes". The 66 series eyepieces are a bayonet fit I'm pretty sure.
