IC5070 - Pelican Nebula (Voirol Christian)

IC5070 - Pelican Nebula

My first and last attempt with 1200 second pauses. The images were never sharp. I went back to 600 seconds in NB and 300 seconds in LRGB which I mastered more or less correctly with my AZEQ6 mount.

PixInsight Post-TT :
Nebula without stars (NB) : ABEDiv - ABESub - Linear StarNet (stars removing) - LinearFit
LRGB All Stars : For each channel : ABEDiv - ABESub - DBE - LRGB Combination
Nebula without stars (NB) + LRGB All Stars : NBRGB Combination (LRGB + R : 3xSII, G: 1.5xHa, B: 0.8xOIII) - DynamicCrop - HT - Signed

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.
