Good try Kit.

Seemed you have fixed the colour issue already.

The polar alignment was not done so well. Do it carefully next time so that stars no longer become elongated in 5 min exposure @ 50mm. I don't know which polar scope you are using on the Polarie. So try to contact other users to get the tricks.

Good luck.

Thanks LT

The color problem was from DSS white balance setting. I did use a China made polar scope with 2mins exposure. May be I did not correct the axis. In overall I feel like both Polarie and a 50mm lens are well compatible. It is possible to extend the exposure time to 5mins. I am new to deep space image processing. The Barnard's Loop looks dark. I may have to enhance the Red channel in PS.

Again, Thanks LT
