LHA 115-N 78 and its neibourhood in the SMC in Ha

2h30min of integral Ha exposure of the LHA 115-N 78 HII complex [1] (in the middle) and the accompanying structures including

NGC 371 (in the lower left corner),
compact DEM S131 HII region [2] (in the middle upper area),
one LHA 115-N 80 HII complex [3] with some very interesting structures inside (in the upper corner)

- all located in the "NE end" of the Small Magellanic Cloud (SMC). Captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope over two imaging sessions carried out on Jan 1 & 5, 2024.

Partial star suppression is applied. Lots of fine structure details are recovered here, especially in the version with full star suppression (revision B).

The cropped version of the LHA 115-N 80 HII complex [3] with full star suppression is shown below at 200% of original resolution:

A narrower FOV view of the LHA 115-N 78 [1] obtained with Chilescope T1 instrument is also available under [4].

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.
