Description

This picture of IC63 (Ghost nebula) was shot in several sessions between November and December 2022 with my TS 100Q Quadruplet APO (580mm). In my last session, I had some guiding problems due to a defective mount. For me, it was difficult to photograph because of the contrast of the dim structure against the gamma-Cassiopeia star.
I made about 200 picture of 180sec and about 50 pictures of 300sec.
I played around with several functions of Pixinsight.
Esspecially the photometric Color Calibration, the ColorCalibration  and the new BlurXTerminator-tool by Russell Croman. So I could extract more information out of my raw data.
Until now, I haven't been able to avoid the circular artifact around the bright gamma-Cas star.
