Description

First light on my WO Zenithstar Z73 w/ P-FLAT73A.

Skies have been garbage this winter, so I was excited to have a few hours to try my new setup.

I think I have some issues somewhere in the image train, as it is pretty evident that the frame isn't flat. Any suggestions on how to improve this? Stars look pretty good in the center of the photograph to me, so I feel like it might not be due to poor guiding.

PI Process:

* Calibrate
* Cosmetic correction
* Subframe weights
* Local norm
* Stack + Drizzle
* DBE, MLT & stretch
