Title: Attempt to enhance fine Ha details for wide angle image of SMC by continuum subtraction using the R exposure obtained earlier

Description: 40min of integral Ha exposure of the Small Magellanic Cloud (SMC) with immediate surroundings captured remotely using Telescope #4 (Nikkor 200mm f/2, FLI Microline 16200) system of ChileScope observatory on Nov 22. 2020.

Continuum suppression applied using 17% of the R component of the image [1] (15 min integral exposure) obtained with the same ChileScope #4 instrument on Oct 7, 2020. Stars were not eliminated from the images intentionally to give plate solver a chance.

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.
