Masuyam 60mm. 48 degree...

[Westmoorland]

...Who would use such an eyepiece, and why? Perhaps it could serve as a focal reducer in a big SCT, but at a price nearing £700, why not buy a small ED refractor instead? 

[Don Pensack]

That's a good question.  It also isn't 48°, it's 43°.

The goal is to get a large exit pupil, low power, and wide field at the same time in an instrument not designed for it.

I like your thinking on the small ED refractor--it can even be mounted piggy-back on the large SCT.

When I had a C9.25 my 42mm LVW was as wide as you could get. It had a small amount of vignetting. x56 and about 1.25°. However, in an f10 scope, far more inexpensive eyepieces would work well.

I'll be getting a Masuyama 32mm 82 degrees for my low power. My Baader Morpheus 14mm is my only premium current eyepiece and I think I'll get the Baader Hyperion zoom for everything else.

In what scope do you plan to use it?  It performs best in slower scopes (SCTs, Maks, CCs, slow refractors, etc.).

Celestron 9.25 XLT. I haven't even got anything to frame the lunar disc at present.

You won't get a field of view any wider than that with a Tele Vue 55mm Plossl at about 1/3 the price of the Masuyama 60mm

I have no intention of buying the Masuyama 60mm, but was curious about what kind of user would. The 32mm caught my attention because it has the same specs as the 31mm Nagler but is built without the enormous bulge.
