Hi all,
I'm aware of the maximum exit pupil that should be allowed for should lie in the range of 6mm to 7mm. For an f/10 SCT that would mean an EP range of 60mm to 70mm. Are there design limitations within the SCT that would preclude the use of such eyepieces?
I ask as I've
come across this eyepiece on ebay from Russell Optics.
Does anyone have experience with this eyepiece too? Such an eyepiece would give me close to 2 degrees AFOV.
Cheers,
Mental.
