LDN 79x and 80x (constellation Vulpecula) and Tulip Nebula (constellation Cygnus) (AstroHannes68)

LDN 79x and 80x (constellation Vulpecula) and Tulip Nebula (constellation Cygnus)

Dear Colleagues,

was not sure if I should poste this panorama (no mosaic).

The red object (right hand side) was 1st catalogizised by Steward Sharpless in 1959 the Tulip Nebula in constellation Cygnus (SH2-101). Details of this fascinating object can be found at https://en.wikipedia.org/wiki/Sh2-101.
Of course the session (2023-09-09,10) took place in the garden of my parents!

Image data:
309 x [60s, F2.0-F2.8, ISO3200, Z6, Samyang 135mm F2.0].

PI processing:
Step 1:
I = WBPP, BXT, GXPAI, DC, IS, SPCC, NXT, HT, M (CT), IM (LHE).

Step 2 (SXT):
n = SXT (I) - N, NXT, LHE, M (CT), NXT, SCNR (0.75 x g), HT.
s = SXT (I) - S, CMS, SCNR (0.75 x g), M (ACDNR), CONV.

Step 3 (PixMath):
PM (1.1 x n + 0.9 x s), HT + magic.

That's all - very simple!

CS and dream of the Tulip Nebula ;-)

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.
