Red and Black

With this image I wanted to capture two very different objects of the deep sky. Barnard 150, or Seahorse Nebula, is a dark molecular cloud in the middle of the frame, totally not transparent to any visible light from background stars. Sh2-129, also known as the Flying Bat Nebula, is the glowing red emission nebula, and actually only a part of it, one of the "wings", fits in the image on the right side.

It was a very difficult task for me to process the data, as this part of the sky is close to the Galaxy plane and contains lots of stars, which totally dominates the image when captured with a small doublet refractor and broadband filters. So, quite a lot of star reducing was applied. Also, background dust surrounding the B150 is very faint and was tricky to process. Not sure if I managed to keep any sorts of real-life color in it, so better not to use it as a reference. Flying Bat, on the other hand, is relatively easy to capture with an H-alpha filter, even the more dimmer outer region, at least at an average Bortle 5 site.

Imaged for 11 different nights in September 2021, only first date for each filter specified in tech details.

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.
