I always thought those were some cool classic eyepieces, Nice eyepieces Terra.






I always like the old eyepieces and the color coded Sears were my favorites. Not quite up to the Naglers in terms of all around performance, but you could take them apart and put them back together on a regular basis without a PhD in probability theory.

Simple is good.

I was in S&S Optica today. Cathy's store is about the only astronomy shop we have in the Denver front range area. Cathy has a true passion for astronomy.

There in the display case was this unit with typical reasonable price, and it just happens to be the one I didn't have. I'm tickled yellow. The glass is excellent.

Thats a great collection Terra.

I still can't help wondering about a white one though.
Have we decided white was pre-1970 18 or 20mm and changed to yellow, or in fact has yellow always been 20mm and a white 18mm exists.
We know white did exist or was planned because of the white port on the turret.

I checked Astro Optical catalogs around the same time period 1969-70 and all jump from 12.5 to 22-25mm.
The only 18mm I could find is listed for a Newtonian and is a Orthoscopic.

I also checked a few Towa refractors and found the same, 12.5mm and next is 22mm.
Bushnell (circle T Towa) lists a K21mm.
Unitron lists a 18mm (12.5 18 25).

I never really thought about these to much. I have a small collection of them.
They belong to my Sears 6339-A 76 mm kit, the grey one is in the diagonal. I have the rest in another set that I collected over the years. Neat stuff! Its good to know I am not the only one that has a couple of these in a box. I think this set is made by RA Royal Astro, Right?

Thank you Robert. Yes, I do believe that there is a white one out there and also an 18 mm. I have heard mention of both and other evidence makes me believe it. For one, an 18 mm would logically fit in the series between 22 (or 20) and 12.5. Then we have the white socket on the the Sears version of the Unihex. My belief is that the white 18 became the yellow 20. But only one of our friends here can answer that question for sure. Maybe someone has a white 18 lurking in a "junk box" or maybe one of us will come across it in some future find.

Clint, though they bear no manufacturers mark, you may well be right because these Sears eps seem to be a cut above most of the run of the mill 0.965s of the time. Especially the two Kellners. They are excellent eps and up to Unitron standards in my book.

I thought I had owned a yellow 18 but it was in fact a 20mm. My mistake.

Terra, great classic collection there! It is so cool that a CN'er responded so quickly to your request. I find that often here myself. This website is a great resource in tracking down odd items. I just recently picked up a spare Curt Gowdy Jason 313 Discoverer with mount complete with accessories from a fellow CN'er as an identical spare to my childhood Jason...how cool is that!? I look foward to sharing it side-by-side with a child someday as their first scope, cutting their teeth as I did, so many years ago!

Absolutely T.R.! This website/forum is the best. Not only for tracking down obscure items, but for the tremendous wealth of information that we possess and freely share with each other, the spirit of community, the shared values, and the inspiration to try out and find use in what others have discarded. I love it!
