How do you find the Ethos in your 12" Dob?
Are stars sharp to the edge of the FOV?

I used a couple of Ethos in my old 12' f5 and had no dramas with the sharpness. The field is so large that you really don't notice the edge while observing, but when I have checked it seems sharp. Also when observing, and others have commented on this, the image at the centre is noticeably sharper. That may just be a case of heightened expectations but I am convinced that the image comparing a 13mm Ethos to a 13mm Nag, the Ethos was sharper and more contrasty.
