L = 216 x 120 s = 432 min
R / G / B = 42 / 31 / 38 x 180 s = 333 min
H-alpha = 46 x 300 s = 230 min

AOM 160/1600 x 0,75:
Mai 2023  L = 32 x 180 s = 96 min (QHY600)
März 2019 L = 1108 x 3,5 s = 65 min (ASI1600mmc)  >> used only for the cores <<

total 19 h 16 min

Leider gab es im Frühjahr kaum klare Nächte. Für neue Aufnahmen von M51 hatte ich daher nur einmal die Gelegenheit. Die 1,5 Stunden Luminanz haben sich beim Summenbild deutlich bemerkbar gemacht.

Unfortunately, there were hardly any clear nights in spring. So I only had one opportunity to take new pictures of M51. The 1.5 hours of luminance were clearly noticeable in the overall image.
