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].

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.
