Description

3h 8 min of integral Ha, OIII and B exposure of the superbubble in the LMC [1, 2] revealing fine structures both inside and around the bubble - captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 3 imaging sessions carried out on Jan 14, 19 and Feb 16 of 2021.

The Ha, OIII, B band exposures are mapped to RGB channels, then put through photometric color calibration of Pixinsight, and finally separately color corrected in Photoshop.

A wider angle view for this object obtained with T2 instrument of Chilescope [3]. Even wider angle view for the LMC in general (in Ha) featuring this structure was also obtained with T4 instrument of Chilescope [4].
