The Lobster Claw Nebula (SH2-157)

SH2-157, also known as the Lobster Claw Nebula, is a bright emission nebula located about 11,000 light-years away in the constellation of Cassiopeia.

 

I started imaging this target in November 2024. Unfortunately, due to bad weather, I haven't been able to get back to it as it has now disappeared behind a large tree on the North/NW. I may get back to this target in 2025.

 

I acquired this image with:

 

* William Optics FLT132 telescope with the FLAT8 0.72x reducer/flattener.

* ZWO 2600MC Pro camera.

* Antlia ALT-P dualband 5nm Ha & Oiii filter

* Optolong L-Ultimate 3nm Ha & Oiii filter.

* ZWO AM5 mount with ASIAir plus.

 

Pre and post processed in PixInsight and Affinity Photo 2.

 

Total integration of 7hours + 35 minutes over two nights.
