Description

Love this collection of DSOs in this frame - the Lobster Claw Nebula (SH2-157), Bubble Nebula (NGC 7635), beautiful open cluster NGC 7510, and the star factory Northern Lagoon Nebula (NGC 7538 - home of the largest known protostar).

Used the ES .7x reducer (FL: 666, FR: 5.2) to get all these beauties in a single frame - first time publishing anything reduced and need to dial in the back focus. But, quite pleased.

5 hours each of Ha, OIII, SII (300 seconds, 0 gain)
12 minutes each of R, G, B (30 seconds, 0 gain) for stars

Used Bill Blanshan's SHO Normalization Pixinsight script for SHO tuning.
