2" 90° Apparent Field Eyepieces Announced

I just looked at the Burgess Optical web site (burgessoptical.com) and
noticed the announcement of "Hyper Wide Angle" eyepieces, with a 90°
apparent field. There's a 29mm and well as a number of lesser focal
length eyepieces. No photos or prices yet, or any hint of the lens
design.

My experience with Burgess has been excellent value for the money. But
I do wonder about the optical characteristics of this eyepiece.

Clear skies,

Probably best to take the wait and see attitude if something isn't currently
yet available. Burgess Optical has been somewhat optimistic in the past about
delivery dates...

Here's some more info from Bill Burgess: It's a 7-element design, all
ED glass,"broadband multicoatings on all air-to-glass surfaces", and
pinpoint stars to the edge down to f/3.5. Availability is at least 60
days out.

The part about pinpoint stars to the edge of a 90° apparent field 29mm
eyepiece sounds very attractive. Maybe some of our eyepiece design
mavens can tell us why this is either impossible or comes at the price
of field curvature, loss of contrast or some other desirable optical
characteristic. Or not.

I have a 30 mm Ziess with an 88 d FOV, and there is a 30 mm Lietz with
either an 86 dFOV or an 88 dFOV. These will pop up from time to time
on the various auction houses on the web, and are of known quality
(e.g. excellent) optically.
