SH2-157 Lobster’s Claw Nebula


Mark Griffith

Swindon, Wiltshire. UK

Teleskop service 8″ Boren simon power newtonian, Skywatcher NEQ6 pro mount,Atik 383L+ camera, motorised filter wheel and Astronomik filters.

Emission nebula on the border of the constellations of Cassiopeia and Cepheus.

Trying another object on the Sharpless catalogue. Sharpless catalogue full of interesting nebula suitable for narrowband imaging. I’ll certainly be imaging more objects from this catalogue in the future.

Not many clear nights this month in Swindon so had to settle for a hydrogen alpha image.

Was planning to do a full hubble platte image but my oxygen data was poor with gradients. I suspect the oxygen filter doesn’t like the light pollution filter I’ve added to my optical train this month.

Ha image with 2 hours and 5 minutes of data. 25 x 5min Ha 2×2 bining.
