William Optics Megrez 90 Fluorite Doublet Owners - Pros' & Cons??

[AlexN]

Nice looking instrument and at a very nice price, Just wondering if anyone on here uses them? Be it for Imaging or Visual, and if so, what are your opinions? I've read a few reviews online, but nothing beats IIS input in my opinion..

This is where "you" come in (provided you either own, or have owned a Megrez 90FD)

Thanks for any input.

Alex.

oops..no I don't but I do own a WO 66 pretzel and a WO diagonal and can say the quality is brilliant on both

When I get home I'll post some terrestrial images I took with the 72 the other day. It would definately benefit from a field flattener (the WO II 0.8 isn't any good for it but the WO III is recommended) using a DSLR. The CA is minimal.

I have unfortunately not been able to do too much with my Megrez 90 lately, however it is very nice eye candy :) .

I had no luck with the WO Flat III with it, due to heavy astigmatism in the corners, and ended up getting the Borg 0.85 DG-L. It has given me very flat images without any sign of astigmatism. However, this cost me 50% of the price of the scope, so keep that in mind.

Construction, finish, and tolerances all seem very good to me. If you do end up using the WO Flat III with it, you just need to throw out the outer 1/4 of the frame on a DSLR.

If you want to stop by some time and have a look, you are welcome to.
