This will be my last go at correcting the stars on the Seestar S50 image that had some star trailing that produced horizontally oval stars. This time I used all of the 2h worth of 30s data for the nebula from which I removed the stars. Then I used the stars from an image integrated from the best 21 minutes worth of 30s exposures which had no, or very little elongation; then I corrected these stars by 1 pixel using a method I have described in workflow 3. Then I added these stars back to the 2h worth of nebulosity. I am satisfied with the result. For my next EQ Seestar S50 experiment, I shall use 20s exposures initially as well as the official Seestar fluid head wedge.
