Description

73min of integral Ha, OIII and B exposure of NGC 1903 open cluster in the middle of the LMC with many surrounding structures captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope observatory, over 2 imaging sessions carried out on Jan 4, 2021 and Jan 12, 2021.

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


The H II region surrounding NGC 1910 here is "N119 (formally known as LHA 120-N 119)" [1]:
