From Auriga to Perseus – 30 panels wide field mosaic SHORGB

Revision title: Sharpened

Here is a mosaic of 30 panels, composed in LRGB with hybrid palettes in true and false RGB SHO colors. Raw data was captured with red, green, blue, and 5nm Halpha, OIII, and SII filters.

The raw data used was captured with the different filters over several years from 2013 to 2023.

When capturing nebulae IC405 and IC410 in 2020 comet C2020 M3 Atlas was passing by, I inserted it into the mosaic below the Flaming Star Nebula where it passed on the evening of 10.12 .2020.

The original image resolution is 298 megapixels for a field of 29° x 10°. 298 megapixels is too big for my AstroBin Premium subscription, so I had to reduce its size to upload it.

Total exposure time on all filters = 184h24m

The hybrid palette which mixes the Hubble SHO palette (SII = Red, Ha = Green, and OIII = Blue) with the RGB palette makes it possible to distinguish the distribution of gases of matter in the nebular structures while the RGB palette in true colors makes it possible to color stars and deep sky objects that are not HII zones while respecting the colors visible to the human eye.

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.
