North America & Pelican Nebulae, NGC7000 and IC5070

Darkness and clear skies are in short supply this time of year, but I managed to get a few hours in on the North America and Pelican combo this month. I'm continuing to use my Redcat since it lets me get in a lot of content rapidly, especially in Cygnus where the interesting content is endless. I really didn't get any useable weather last summer, so it has been fun to get to explore it finally.

The temperature cooled enough during the night to de-focus the stars just a little by the end of the night - not enough to do serious damage, but it left a slight greenish edge around the larger ones that took a bit of playing around to deal with. Here, I found that separating the star layer with Starnet++ was the strategy. Interestingly, Starnet didn't work at all on the linear (un-stretched) image, so I had to roughly stretch it first and then Starnet worked perfectly. Fortunately, this dataset was incredibly smooth anyway; I think the nebula is intrinsically quite bright, but this is probably the lowest-noise dataset I've gotten so far. I did hardly any noise reduction on the nebula layer at all.

Description: This is the starless version, which I wanted to upload since Starnet++ did so well on it.

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.
