Hi All,

I've been looking for a good quality 1.25" high power eyepiece for my 80mm f/5 iOptron Refractor to use for planetary and double star resolving.

The choice so far is a 6mm eyepiece (good eye relief and sharpness) and a 2.5x ED barlow. This will give 167x (2-2.4x dia of lens in mm) which is around the practical maximum. I have a 3x barlow that I got with the scope and could get 200x if seeing permitted, but this is not essential.

I was looking at Guan Sheng for the 2.5x barlow and Long Perng for the 6mm Planetary eyepiece. I also thought I'd get a Guan Sheng or Long Perng erecting 90° diagonal.

Does anyone have any views on these products? (I've heard that Long Perng manufacture for Williams Optics)


Thanks,

Glob.
