The Lobster Claw (Sh2-157) and The Bubble (NGC 7635)
After bouts of clouds and storms, I’ve managed to put a wrap on a new project. This is a two-panel mosaic of Sh2-157 (the Lobster Claw Nebula) and NGC 7635 (the Bubble Nebula) in the constellation Cassiopeia. Last year I had the opportunity to work on a project dedicated to the Bubble Nebula, but this year I wanted to capture some of its surrounding company. Any mosaic has its troubles and this one was no different in that regard, but I’m pretty pleased with how it turned out.
