The Lobster Claw Nebula (also known as SH2-157) is an emission nebula in constellation Cassiopeia and it is located about 11 050 light years from earth. Visible in the image is also the open star cluster NGC 7510, the planetary nebula LBN 537 and the smaller open star cluster with the Wolf-Rayet star WR 157. Overall, a very interesting section of the night sky.
This object is new for this season, and I initially thought that there wouldn’t be enough time to gather data on new objects. At the time of editing this video the astro darkness is gone (ended on April 11th 2024 here at 63 degrees north) and there will be no new data gathering. I still have some data to process so stay tuned to the channel.

Data for this image: 44x300s S-II, 74x300s Ha, 45x300s O-III.
