But which one? The 10/8 spacing would be a bit close, but I prefer not to leave a gap between the 10D and the 6D, as that's the difference between 150X and 250X on my 12" dob.
I'd gladly add a third Delos if Televue made a 7mm Delos. But I guess they decided many buyers who have the 10mm Delos would forgo the decision between the 8mm and the 6mm Delos and just get both, so they're set up to sell more Deloses ("Deloi"?) than if they went from a 10mm straight to a 7mm.
Quote:One thing I would to see in the future--ES? Televue? Hope you're listening--is splitting the difference eye-relief and AFOV-wise between the Delos and Ethos classes and making a 17/18-mm eye relief, 82-deg "Type 7"-Nagler class eyepiece. I'd be willing to bet ES could market something like that for less than the cost of the Delos line.Clear Skies,Phil

Quote:Interesting line-up, you don't see many Denks about. How do like them vs. the Pentax?
Quote:Phil and Dave, perhaps you are forgetting the Type 4 Naglers? The 22mm has 19mm of ER and the 17/12 have 17mm. So no type 7 needed BUT they need to extend the Type 4's down to lower focal lengths perhaps.
Quote: But I would like ES to try their hand at a 70* AFOV 20mm ER eyepiece line, that's what I would like to see and I surprised they have not done it yet. Oh yes, and some Type 4 clones as well.
Quote: Option 1--Keep the 2X barlow and get a 7mm Pentax-XW.

Quote:What purpose is the 4X PowerMate going to serve? If you use the 14mm Delos + 2X Barlow, you'll get the 7mm F/L.Then when you finally do find that 7mm XW, the 2X Barlow can go. Or am I missing something?Mike
