4h 50 min of integral Ha, OIII and SII exposure of NGC 18[72, 74, 76, 77, 80, 81] region in the LMC captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope observatory, over 5 imaging sessions carried out on Apr 7, 9, 11 and May 8, 9 of 2022.

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

The wider angle view of the region is also obtained earlier with T3 instrument of Chilescope [1]. Even wider angle view to the LMC (in Ha, in which this region is plainly visible) obtained with T4 instrument of Chilescope is available in [2]:

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
