Thank you for this amazing list. Are the little TV Zooms (2-4mm and 3-6mm) discontinued? I ask because they're still widely available from retailers.

They're in the list between the Ethos and Nagler Type 4's as "Nagler Zooms".
Still made and stocked everywhere.

Between this and your "Best of Deep Sky" list, it's amazing that you have time for anything else! Keep up the good work!

My earlier version of the spreadsheet had calculated columns for magnification, exit pupil, and true field. You just posted your telescopes focal length and f/ratio at the top of the column and the spreadsheet automatically filled everything in.
I'll post instructions for how to add those columns to the spreadsheet tomorrow.

OK, I am attaching the 2013 Buyer's Guide to Eyepieces again.
This new version has calculated columns for:
*magnification
*exit pupil
*true field in degrees (you can convert to minutes by multiplying by 60)
All you have to do is insert your telescope's focal length and f/ratio in the two top cells with red lettering.
*NOTE* this will not work with eyepieces that have a range of focal lengths or a range of magnifications. In those fields you will see errors.

My Sage Calculus/Photography/Astronomy Instructor from High School....yes small town, but this man is exemplary in all mentioned fields. He uses several film and DSLR 35mms, Also has a Hassleblad 2.25x2.5, and a Linhof Technica 4x5. He has had an extensive color and black and white darkroom since I met him in 1978, and has a 10" Newt that I first saw Saturn, Jupiter and Andromeda through.
I place all of that ahead of what he has recently told me, to establish his "bona fides" in the world of optics, both near, and at great distance. I had always told him from waaaaay back that I wanted a Contax 35mm, because they came with Zeiss lenses, which he always sang the praises of. I believe after that, in the camera world, Rodenstock and Sinar were his Choices...oh and Pentax, though their camera lenses aren't as highly prized as their telescope oculars.
Anyways, He told me just this last fall that Zeiss quality has fallen through the floor. I cannot remember if he said they were bought out, or what happened, and how long they've been sub par. I will contact him this evening or tomorrow to get his insight, but he told me that the people buying newer Zeiss lenses are wealthy impressionable amateurs. If true, it is indeed a shame that the greatest name in lenses has fallen away into the pack....yet still with winner's circle prices.
More to come as I learn, or others contribute.

The attached spreadsheet includes all non-discontinued after-market eyepieces currently available for sale by retailers.
The manufacturers catalogs are larger, but if no retailer is currently selling a particular eyepiece model, I did not include it on my chart.
All the normal information is included and prices are as I found them over the last month.
If I have inadvertently left off a brand or model, please send me a private message and a link to the website where I can find information. I can always update this.
Note that I purposely left off 0.965" eyepieces, Huygenian, Ramsden, and Super Ramsden eyepieces as I do not believe these would be of interest to people reading posts on Cloudy Nights.
I also left in the Pentax XW eyepieces as we just received word these are discontinued but there are a lot in the retail sales bins and will be for a while.
Great stuff
thanks !!
