Thanks Joe!

@Stefan,

At this stage, for low power I’ll use a 2 inch GSO Superview 30mm 68 aFov but may upgrade in the future to the closest focal length in the ES 82° series or a second hand nagler. For medium and high power, I’ll use the 1.25 inch xcel lx at 60 aFov, I have the 25,12, 9, 7 and 5. But I’d be surprised if the seeing is ever good enough for the 7 and 5 on a widefield instrument.

So I guess, the 30mm, 25mm and 12mm would be used more often than not as I assume their exit pupils should be good for DSOs at either f/5.5 or f/7.
