NGC 1788: HRGB

OTA: PW17” f/6.5
Camera: FLI CCD of some sort
Observatory: Deep Sky West

Exposures:
R: 15 x 600 sec
G: 14 x 600
B: 17 x 600
H: 21 x 1800 sec
Total Exposure time used:18.2 hours
Image Width: 40.25 arc minutes

Processing:
PixInsight, Topaz Studio2, custom scripts for image weighting extraction of the H emission line, and star replacement. The data set had more uniformity of quality (which appeared of a high level) than I have encountered previously.

Color:
This nebula has a focus point in the center, but the red arching nebula generally lacks any structure or detail in a simple RGB rendering. An HRGB image is about the same. The entire image has a blotchiness, which is perhaps accurate but conflicts with trying to maximize the image detail. Maybe that is why so many Astrobin versions avoid showing much detail?

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.
