Description

The Lobster Claw Nebula (Sh2-157) and the Bubble Nebula (NGC 7635) are embedded in an large area of extended hydrogen clouds. I took all the light images on the incredibly clear nights in August/September 2023 from our garden in Berlin. This resulted in almost 20 hours of exposure time. The image processing was a bit of a challenge because the wide field taken with my Samyang 135mm F2.0 ED combines some very bright nebula complexes and many faint nebulae. The final image is a blend of Red = (Oiii^~Oiii)*Sii + ~(Oiii^~Oiii)*Ha, Green = ((Oiii*Ha)^~(Oiii*Ha))*Ha + ~((Oiii*Ha)^~(Oiii*Ha))*Oiii and Blue= Oiii. This enabled me to achieve a good balance between the red and green parts of the nebulas.

I hope you like it.
