Description

Since we're all stuck at home anyway, I thought I'd process some old images hiding on my hard drive.
This is a busy area of the sky. The Lobster Claw is the main feature but the bright nebula NGC 7538 wants to be noticed, as does NGC 7635 with the Bubble Nebula and the open cluster M 52.
