The Boogie Man in Orion

Link: https://apod.nasa.gov/apod/ap200221.html

LDN1622 is always an interesting object to me. The most interesting part for me is the Parsamian 3 (HBC515, HD288313) area. Anyhow, it looks like a fish trying pretty hard swimming toward the Orion nebula and about to cross the red river of Barnard's Loop...

It has been a year since the last HaLRGB image. It's about time.

On and off I captured about 50+ hours of Ha data from the backyard (Guess I had nothing else in mind at that time. LOL). But only got 7.6 hours of RGB data from Atoka dark site. I assume the dark site data is far away from enough. But can't resist the temptation to take a peek what it would look like. Then here it is.

As expected the dark cloud is not showing up enough. I consider this is a project in progress. More data will be added in next couple of years to get the "desired" result.

Lacking RGB data indeed push the post-processing to the limit. A lot of Range Selection + PixelMath combinations used to extract every single drop of the signal. The starless version of the RGB masters look exactly like heavily pounded battle ground - all kinds of holes. :)

The synthetic luminance master was created from starless Ha master joined with the luminance data extracted from combined RGB master. Another fun process to put the pre-main-sequence star area back into the final luminance master.

Well that's it for now. Looking forward to the next round on this target. 👁

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.
