Collimation Results & CCDInspector

[Freff]

After some resent collimation difficulties on my MN190, I seem to have had some success. A couple of screen shots of CCDInspector show, I think favourable results.

I would appreciate it if someone could analyse them for me please.

Also attached is an untouched image of the subject. IIRC it’s a single 180 sec guided.

Many thanks.

Should I have posted this elsewhere?

What camera are you using mate. Lots of curvature there that I don't get with a large chip CCD.

Other than that, it looks very uniform and nothing flats can not sort out.

Hi Cat, it's the Canon 5D2.

This is the first opportunity I had to use the MN190 since I spoke with you a couple of weeks ago.

Tony, im not over familiar with CCD inspect however looking at the test image the stars look to be in good shape out to the edges, I dont see any field curvature ?? The vignetting is expected on a sensor that size.

I think your on to a winner combo there.

Many thanks Astroscot2 for your observations, reassuring.
