[ATM] RE: ATM Schiefspieglers in Oslo LT

["Donald Good" <donald.good@comcast.net>]

I sent the following OSLO evaluation graphs of 8" Stevick-Paul telescope to
ATMsite.org, but it was never posted.  Now that I have a small web site, I
posted it there.

Note especially the small spots at the in-focus position from on-axis to
edge of field compared to the Airy disk (circle).  Compare these with the
Parabolic Spot diagram which shows coma at edge of field.

Clear skies
