Thanks Mark,
I checked the triangles yesterday and made sure they rock evenly.
I tested yesterday again with a wide ruler instead of a hand and it appears that my earlier test was inconclusive and the rotation of primary mirror itself (cell in the same position) changed the direction of astigmatism.
There is a little crack at the back of the mirror going 2-3mm deep and about 2cm long. I guess I will call the shop and ask them to take care of it under warranty, the astigmatism is just too strong.
Thanks for all replies. I'll update the thread once the issue is resolved.
Alex
