    Default Eye Relief of 22mm Televue Panoptic and why it was discontinued



    This is an eyepiece I am seeing on the used market and would definitely consider buying, but I am having trouble finding information on the eye relief. I've seen 15mm listed in one case and an 18mm estimate by someone else.

    Also, does anyone know why this eyepiece was discontinued? I've only seen positive things written about it, but I'm curious why it's no longer part of the Televue Panoptic line up. Is there anything wrong with it?

    Eye relief is 15mm. Why did they discontinue it? Only Uncle Al knows. Maybe the close 24 Pan was a better seller. I love mine and will not part with it.

    Thanks for the quick reply. Unfortunately, with my astigmatism, I need to use my glasses with that magnification (unless I get a Dioptrx) and that eye relief is too small for me. My ES 8.8 has 15.6mm eye relief and it's fine without glasses, even though there is quite a bit of kidney beaning if my eyes are not in the right position, but with glasses, my FOV is probably 50 degrees, if not less.

    I have the 24 Pan, which has the same published eye relief, and if I keep the eyecup folded down, and press my glasses firmly against it, I can see the entire 68 degrees, but only barely. I may depend on your particular eyeglass design, I don't know.

    I went and spent money on the Dioptrx and Panoptic adapter, but it turned out to make things worse for eye relief...i.e. even without my glasses on, I see less FOV because the Dioptrx eats into some of it. Live and learn! (or is that spend and learn?)

    In my dob it shows some coma, but with the paracorr.....tops in my book. Works fine in my f10 frac too. Mine's not going anywheres. Go to any dark site and you'll find quite a few of these in people's kits......
