Description

This image was taken over two nights in late May 2022 using an ASI2600mm Pro, Astro-Tech 80ED (on an EQ6-R mount) and a Hotech Field Flattener. 

The image comprises:

Ha:      21 x 300s 
R:        12 x 180s
G:        12 x 180s
B:        12 x 180s

Total exposure time was 3 hours and 33 minutes. The image was processed in PixInsight and tweaked in Photoshop.

Decided to try this set of objects while waiting for Sagittarius to rise. Hadn't imaged Sh2-9 previously.
