Sh2-157, also known as the Lobster Claw Nebula, is a faint large emission nebula visible in the constellation Cassiopeia. It is located in the Perseus Arm. The northern part of the cloud has a ring-like shape, caused by the stellar wind of several giant stars, while the southern sector appears excited by the light from spectral class O stars. Within it lies a cluster of very young stars.
The frame also has the Bubble Nebula in the upper right. A nebula I captured a while back.
The camera used for this was the new Touptek SkyEye AC26_Plus and a 7nm dual narrow band filter. 75 subs of 300 seconds with 25 each darks, flats and biases. Total integration time of 6.25 hours. I would like to add another 14 hours to this to get a lot more detail.
