Looking for a planitary eyepiece to bridge the gap between a 9mm and a 5mm. Will be used in a 14.5" F/4.3 Dob. FL= 1.58m or 1.817m with TV ParaCorr. Don't really want to spend enough for a new Radian or Nagler. I'm looking for a 1.25" eyepiece that doesn't cost a fortune, or weigh over 12oz, that has image quality similar to a high quality ortho, 50° AFOV, and at least 14mm eye relief. Have been considering the VL's and Celestron X-cel but have herd many reviewers knock their immage quality. Eye Relief and comfortable viewing are "almost" as important for me as the immage quality. I have tolerated the 12mm eye relief of my 9mmT6 Nagler, but would not cope well with anything any shorter than that. Have been content with the immage quality and eye relief on my 5mm LVSW, but find it larger and heavier than I would like. Reccomendations????

Hi James.
I'd second John's suggestion, although my stragegy has been a little different. I use an 18mm ortho (The UO model has good eye relief for glasses, at least for my glasses.) With that eyepiece, I use a 2x barlow to get the equivalent of a 9mm. On top of the barlow, I use 1" and 1.6" extension tubes to get the equivalent of 7.5mm and 6.7mm focal lengths. If you decide to go with the Klee, it's a good barlow and, coupled with the 18mm ortho (or maybe even a 25mm ortho?), would get you effective magnification in the range you're looking for and give you good eye relief. You might find either approach satisfactory.
Good luck,
John
