ATM Star test

["Art" <mock47@accessbee.com>]

Hi,
I attempted to star test my freshly polished first mirror 10", F/7.  I think
there was too much air turbulence as the stars I looked at seemed to scatter
their light with no evidence of rings.  I could, however, focus in and bring
the light to a fairly sharp point.  Racking in and out merely created a lot
of flaring and jumping around. I chose another bright light and found myself
looking at Saturn.  With a 9mm eyepiece Saturn was sharp and quite round and
I could clearly see the space between the rings and the sides of the planet.
I was surprised to get this clear view with an uncoated mirror. Does this
hold promise of a good figure or is it common?
