Download CCD Inspector from CCDWARE. It will show exactly what is off
including curvature, and out of square. My used STL 11K was out of square a
couple
of thousanths while in NM imaging, funny how little hardware stores don't carry
.001" shim washers for 10-32 bolts! Try it out as a demo first. Keep notes on
what and how much you adjust anything.

Sorry for the late response, I have been out of town on business. Things
went pretty well. We had a few cars drive up with lights but it got better
as it got later. I managed to image three objects. Unfortunately, I think
I need some adjustments in my optical path somewhere. I am using HyperStar
on my C-11 and the stars are not looking to good on the outer edges of the
images. I did take the setup to Dean in Starizona a couple of weeks ago
and he adjusted things, but still seem to have issues. To be fair, I have
a full-frame chip on this, and Dean said it was not made for such a large
chip; Still I think the stars are distorting further in from the edge than
I think they should. I'll need to continue to research.
Here are links to the objects I imaged, no pollution filters:

Hello,
I know most of you are going out to the big astronomy shin-dig this
weekend.
Just wanted to let anyone interested know I plan on being out at the
Massacure Grounds Trailhead Parking
