OK, now that I've stocked up on decent .965 EP, I'd like to find some screw-on filters. Any ideas? I've seen a couple on fleabay now and then, but I wondered if anyone was currently making/importing them.

Are you thinking something along the lines of LP filters? Can't say as I've seen any that size for sale recently, although IIRC either Meade or Celestron offered a deep-sky type filter in .965; however, this was decades ago.

I wonder if current 1-1/4" filters, when removed from their cells, could be scribed with a glass cutter, the outside broken off and thus reduced in size to fit the smaller holders. Old .965 filter cells sourced from moon and sun filters should be plentiful.

I was thinking colors, for planetary use.

Plenty of old sun and moon filters around. SurplusShed has moon filters, new. That's a good idea.

There is a .96 Celestron Red filter up on ebay now..... or for some short period of time until one of us .965 collectors grab it. I would have already purchased it except I spent my monthly allowance.... :(

Since 965s and small scopes go together, I have tended not to use my filters much. There just is not enough light from a 60mm, at least in my opinion. But, it might be worth getting some... what would really be good would be some in the lighter colors, but those would be super-rare. Glen

That's what made me think of it. There's gotta be a source out there someplace.

Maybe he still has some. He lists them. They were never cheap, and still aren't. Glen

.965" color filters are cheap on Ebay. Just watch the ads for a month or two.Look at all the filters because the seller may not know anything about telescopes.

They are not easy to find. The very best ones came from Optica b/c and they offered dozens of different filters. There were colored filters (light, medium and dark), neutral density filters, polarizing, and narrow band interference filters. I have managed to find a few of these and many of them came to me at once by sheer accident. Optica also published a great book on using filters. If you find any .965 filters, buy them.

There's a set of .965 color filters up in the CN classifieds right now. I'm not associated with the seller, just pointing it out.

I missed a 4-filter sale on CNC by not seeing it fast enough. Dang it. But I've got a LPR coming - that should be fun to try given the sky around here these days.

FOUND: Made in China, 24.5 mm

I may have to try these out. EZPak shipping is cheap enough ($2).

The best part: You can still buy screw on sun filters at this site. Yikes!

Sherry Hand at HandsOnOptics says she gets them from time to time, so I guess I'll just keep my eyes on her Used Stuff list.  She's sending an 80A, which was at the top of my Wish List.  A very generous CN member is sending me a couple of "extras" he found in his gear.  After a few months I should have a pretty good set put together, but I sure would like to find an importer.

 

and...a Celestron set went up on Amart today.  CharlieB tipped me to it, and it's on the way.
