RCW 56 / GAL 291.1-02.1 HII region - Evil Martian Head nebula?

Revision title: Version of the image with full star suppression applied

1h50min of integral Ha exposure of immediate vicinity of a small (2.5 arc.min in diameter) nebula identified as RCW 56 / GAL 291.1-02.1 HII region [1, 2] - captured remotely using Telescope #1 (ASA-RC D = 1m f/6.8, FLI ProLine 16803) system of ChileScope during 2 imaging sessions carried out on Mar 18 & 19, 2024.

A wider FOV view of the same area obtained with Chilescope T3 instrument is available under [3].

The starless version of this object has an uncanny resemblance to a certain movie representation of a certain alien race [4], hence the secondary title

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.
