Has anyone bought and had a chance to really use the new 24mm TV Panoptic? I have been looking for a wide field eyepiece at this FL and missed on an old TV "Widefield" on eBay, and now this is out, with the widest possible true field in 1.25". How is it? Thanks.

It's been too cloudy here in Indianapolis to do thorough testing but brief gaps in the clouds indicated this is an excellent eyepiece. Eye relief didn't seem much different than the 19 mm Panoptic but again, viewing was too brief to concentrate on that issue.
One guy in our local astronomy club brought his Nexstar 11GPS. Brief testing with the factory 1.25" prism diagonal caused noticeable vignetting (probably narrowed to ~ 60°). Thus, you may need to pay careful attention to the diagonal used with this eyepiece. I haven't tested this eyepiece on my SCTs or refractors yet to determine if a 1.25" mirror diagonal such as the Televue Everbrite doesn't cause vignetting.
