Re: Can't get less than 1" total RMS

Given that the stars are round, I think the mount is not the culprit. 

I hope you realize that you are imaging at 0.56'' per pixel and that is not easy.

Possible culprits most likely are
1. Poor seeing
2. Poor focus. How do you focus ?
3. Poor optics

Yes, I use a lot of sharpening methods in PI - deconvolution and others.

Can you install demo version of PI and do DynamicPSF on your stars and share results?

Then I can compare with my results.
