Description

1h 40min of integral RGB exposure of a region near Collinder 261 open cluster in Musca, captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 2 imaging sessions carried out on Jan 27 & 28, 2023. The main star of interest is highlighted by the blue cross-marks - this is the star that showed up peculiarly pink in the exposure obtained earlier with Chilescope T2 instrument [1].

Original image shows photometrically calibrated Chilescope T1 exposure.

Revision B shows a composite view of
- Subframe of the RGB exposure obtained earlier with Chilescope T2  instrument [1],
- Photometrically calibrated (using PixInsight tools) Chilescope T1 exposure,
- Manually calibrated Chilescope T1 exposure.

Nothing peculiar was detected in the T1exposure of the region after all.
