Astrophotography Open Cluster

Astrophoto: Beehive Cluster – Messier 44 – 04/21

My 2023 reprocessed version. The Beehive Cluster or Praesepe. Marry Christmas to all who celebrate it.

Messier 44, Behive Cluster

There was no other object until now, where i got data from more sessions than from the Beehive Cluster. I think it were 4 or 5 evenings. The final picture was processed using data from 3 evenings.

In May i processed the data from all 3 evenings with Affinity Photo. I reprocessed the data in december 2023.

Lessons Learned

Since i did the processing a few weeks after i collected the data, i can’t really remember any problems. Dithering worked!
