A superb image of the Lobster Claw Nebula with the Bubble Nebula taken on Monday 22nd September 2025 from Bexley by CMHASD member Kevin Langford.
The Lobster Claw Nebula, also known as Sharpless 157 (Sh2-157), is an emission nebula located in the constellation Cassiopeia about 11,000 light-years from Earth. Its name comes from its distinct shape, which resembles a lobster’s claw and is formed by glowing gas, dark dust, and stars.
To the left of the claw in the image, you can see NGC 7635 – the Bubble Nebula, which is much more widely known. Also visible is the star cluster NGC 7510, above the lobster claw pincers (Chelae).
Kevin’s image consists of 3hrs in total of exposures.
Kevin acquired the image using an ES 102ED APO, 0.7x focal reducer corrector, Pegasus NYX-101, ZWO ASI071, Orion MMAG, L-eNhance filter.
It was then processed in Siril and Affinity photo.
