Hi Geoff
I only recently went for a routine eye check with an optician and was told I don't have astigmatism
I do, however, need glasses for distance vision. If I look up at the sky (just naked eye) I see 2 or 3 moons when I look at the moon.
But my short distance vision is very good. I don't need glasses for reading etc
Everything looks pretty good through a 24mm Pan in my 9.25 (f10) although even then I can see little tails if I'm not on-axis.
I generally tend to use the 10mm Pentax XW, 13mm Nagler T6 and 24mm Pan with my SCT
