I wear progressives but not at the eyepiece. I've found there's nothing like having a Panoptic fitted with a Dioptrx. I suggest you fit your favorite low-power TV eyepiece with a Dioptrx to match your prescription. I use the 27 Pan and my Dioptrx is a 1.0. I agree completely with the Dioptrx chart, and feel I don't see the astigmatism with exit pupils at or below 2mm.

I bought the flippers several years ago from the company in Canada, used them to determine if they worked, then went to my Opt. and got a pair of astronomy glasses in -0.5 diopters. They are great. He suggested making them traditional bifocals which I did. Now I wish I had gone with 'line' bifocals where the entire lower part of the lens is for close reading (think charts). Also I wish I had gone with coated lenses. Mine pick up every reflection of a red headlamp from behind me and bounce it into my eyes, so get coatings on both sides.
I would loan you the flippers but they got lost, I've been looking around for months. If I find them you can borrow them.
Ted,
I take it that using the flippers you found that -.5 was the best "adjustment" to your normal prescription?
If you find the flippers, and you are going to Stellafane or CSSP, please bring them along. However, with the "cheap" plastic glasses so inexpensive I might just order two pair at -.25 and -.5.
I’m looking for something for naked-eye viewing at a dark location, something I really enjoy, but at times find the stars kinda spiky. I can see well enough close-up without glasses for many purposes, and I don’t wear glasses for observing thru a scope, but only for set-up and when imaging. However, with my differing left/right eyes, I always drive others a little nuts when using my bino-viewer which is naturally adjusted for my eyes.
