Peter, do you have a budget, if I may ask? The TV Plossls are very nice at the FL's you have, beautiful sharp views and field, but I really think once you start getting to the 8-11mm range, you are much better off with a 65-70 or more deg FOV, and around 20mm ER. It will transform your viewing experience IMHO.

I fully agree with Malcolm and John B, the 10mm Pentax XW, or the 10mm or 12 mm Delos would be magic, if you could afford one at all. That would give you 100x to 120x with arguably the best contrast, sharpness and field that money could buy (albeit I haven't tried a Delos yet). I'd seriously think about the magnification, FOV, and the objects you like looking at, with respect to each eyepiece, before you buy because it is a lot of money to lay out for one prime EP. Then, later down the line, you could add that prime 2x TV barlow or 2.5x TV Powermate to get high power for planets.

For instance, sooner or later I'll replace my 13mm LVW, and I am putting a lot of thought into the myriad of options - Delos (70deg, 20mm ER) vs Ethos (100 deg, less ER), focal length of 13 or 17mm, then 1.25inch or 2inch barrel also comes into the equation, and what will the final framed picture look like in terms of FOV, magnification and background darkness... and will my 27mm Panoptic become more for less redundant? I have no doubt that we all go through the same process when to comes to 'upgrades' for eyepieces...
