Description

85min of integral Ha, R, G, B exposure of the superbubble in the LMC [1, 2] captured remotely using Telescope #2 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope observatory, over 2 imaging sessions carried out on Nov 16 and Nov 18 of 2020.

The color scheme achieved by mapping Ha, RGB exposures to LRGB channels, followed by the photometric calibration procedure done with PixInsight, applied to whole field.

A wider angle view for the LMC in Ha featuring this structure was also obtained with T4 instrument of Chilescope [3].
