2" 26mm Burgess SWA-- what is the fov?

The Burgess Super Wide Angle 26mm 2" lists a fov of 72 degrees.

Wondering if anyone has measured the actual fov...

I'm asking because I've found that the fovs for some other 2" eyepieces are less than specified. For example, the 32mm Burgess is listed as 72 degrees, yet measured 65. The 30mm 1rpd listed as 80 degrees, measured 70. The 26mm GSO/GTO is stated as having 70 degrees, measured 58. These are approximate, based on star field widths. (For comparison, using the same technique, a 21mm Pentax had exactly the 65 degree fov it is supposed to.)

I'd like a 2" eyepiece in that focal range with good fov, 20mm eye relief for glasses, and for not a lot of greenbacks. (E.r. rules out 24mm Pan; $$ rules out 27mm Pan.)

Hi Larry,

I have a 26mm Burgess SWA. I have only had a chance to use it twice since I bought it 5 months ago. I do know that I really liked the eyepiece, and that barlowed it mage one heck of a 16mm, with even a bit better edge correction. As far as FOV goes I would say it is very close to the 70 degrees. I am keeping my 38mm SWA, but I am considering selling the 26mm as I need to raise some money for a new trumpet. ( I also play trumpet in The Sound of Music for the Leavenworth Summer Theater) My horn is needing replaced...

Back on topic. I like the 26mm, and found that on scopes that were f\5 or slower they looked pretty good. Considering the price... Very good.

Hope this helps. Any questions feel free to ask.

Larry,

It measured at about 70 degrees for me, but maybe what you really need to know is the field stop diameter. I don't remember the number off the top of my head, but I measured it with digital calipers and put the number in a table in my report on Cloudy Nights.
