ATM Star Test Help
Hi
I did a star test tonight and i need some help.
I'm using my 8"f5.5 with a 6mm cheap eyepiece.
I some astigmatism.I don't think its in the primary.
I think it was in the same direction as the diagonal
mirror.It might also be in my eye because it rotated
a little with my eye.Out-side of focase it was
bright on the edge and near the secondary.I
could not see very good in-side of focase because
it wouldn't go in far enough.Does anyone have any
idea of what is wrong?
Thanks,Chris
P.S. I'm going to send off my mirror to Newport to get
coated this Friday.And it's only $25 for my 8"
mirror.Does anyone know what turn around times are
like
from them?
