[ATM] Testing a Scope. i'm astigmatic and myopic

["Ian McKernan" <I.Mckernan@murdoch.edu.au>]

Hmm, if this is inappropos say, but i am after info on a star test of a little 130mm Mak Cass. I have read up that the out of focus image being different inside and out of focus is not an issue like it is for a newt.  However, even when i was testing my first mirror i knew i was always going to see some astigmatism since i am short sighted and astigmatic. I tend to observe with my glasses off since most of my eyepieces re not the best for eye-relief.

The query is that the in focus images at 200x magnification show the stars as crosses?? Anyone have any ideas as to whether this is the scope or my astigmatism??  No surgery has been done, and the myopia is compensated by focusing.  Any opinions welcomed!
