If it is possible I will use a pair of the Ethos EP's. But which is the most useful, without degrade the scope's view quality? Which magnification is the most useful? Thanks!

Ethos eyepieces, except the shorter focal lengths, are not suited for binoviewing, simply because they're too big and heavy. Also, can you reach focus with just the 1.25x corrector or is a stronger one needed? The FSQ has very limited back focus, as we discussed in another thread. Clear skies!

Like Thomas said, it really depends on the object that you want to observe.

I use 8mm for high power; observed with Brandon, TMB Monocentric, and A-P SPL's. All Excellent. Have also used low price/good quality Plossl's with good success. I use mostly the 1.7X corrector; but have used the 1.25X on low power eyepieces. I have used the 2.6X corrector with my f7 and f6.3 refractors with no problems. My preference is for lightweight eyepieces to keep overall weight down. Wes Post Extras:       Doug D.

It is what I often use with my 140 EDF. I also use ZAO II's for pretty much everything else with that scope. The choice really depends on your targets as others have already pointed out but if I was limited to one pair - they would be the 24 Pans with compensators and Barcon.
