Nice image. We can see many details of galaxy. And curious, I am having problem with shape of stars, too.
But I have had some problems with PHD2, and winds.
I did M30, but the stars were very bad. The PHD2 graphic was well full time, with only 0.5 or 1 arcsecond. As in all others works, including the M 70 and M 55.
The shape of stars in M 30 killed the capture. With appearance of drift to the same direction in all 20 frames. It is not normal, and I didn't undestand it.
Maybe focus... flexion of OTA ... collimation ... But I did M 30, M 70 and M 55 at the same night !
Mistery and ghost ! Exorcism ? ! ...
Easy solution: try again !
