Description

3.5h of integral Ha, OIII and SII exposure of the dark clouds in the vicinity of Fighting Dragons of Ara captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 4 imaging sessions carried out on Jul 2, 3, 4, 5 of 2022.

The Ha, OIII, SII band exposures are stacked and mapped to RGB channels in Pixinsight, and finally separately color corrected in Photoshop. The image is intentionally mirrored vertically for better effect.

The wider angle view of the region is also obtained earlier with T5 instrument of Chilescope [1, 2]:
