As long as I have to check the Moon phase for observing night, I'll not give up.

Quote: Quote: Try pulling the eyepiece out of the focuser a little bit... Yes, even if you have to hold it in your hand while doing-- just to make double-dog certain it is truly OUT focus you are needing! If it turns out to be *IN* focus you're short on, then you have a whole new problem...As an alternative thot, assuming you *do* need a 2" extension, perhaps a good 2" Barlow having the lens cell removable (threaded-on) might come in handy?.... so the Barlow's tube can be used, sans-optics, as the "extension".
Quote:For both eyepieces, I added O-Rings so they can now reach focus. I also had to add 2 empty 2 inch filter cells to my 9mm ES 100, so that the barrel is longer and sits better in the focuser. I would have used a 14mm Baader fine tuning ring, but the one I have is too long at 28mm, so the 2" empty filter cells sufficed.See attachments. I hope this helps!

Quote:Hum, the margin of safety seems greatly reduced, is it not ?

Quote:Nice! Aren't you also a collector of vintage eyepieces too?Cheers,
Quote:Just slightly. I have among other a Nagler 11mm T1 and the smoothies NJ Televue widefield series. I have about 30 eyepieces, recent and vintage. Do you have some ?
Quote:If you ever bought a used eyepiece, chances are Marcus had it at one point or another.....Marcus is like the King of Eyepiece Swappers......and we all owe him a thanks for that.........he'd done some pretty decent reviews of various eyepieces written more on a laymen's terms then a lot of techie stuff.

Do you have some ?Hi Pollux556,Unfortunately I do not have any vintage eyepieces. Like Randy said, I swap them out a lot to try others. If I had of saved every eyepiece I have bought, I would have hundreds! I just have four right now. As for vintage eyepieces, or older offerings, I have owned a 16mm flat top Konig, a 2" 32mm Edmund Erfle, a 32mm Konig, a few Criterion eyepieces, maybe a few more. Wish I had of kept them also!I think Bill Rose AFAIK, is the king of the eyepiece collectors, I'm prob the king of buying and selling, LOL!
