This 4 panels mosaic was acquired over 10 nights : 8, 1à, 12, 13, 14, 15, 16 & 17 of october, and 17 & 17 of november.

The process was :

- dark and flat calibrate, cosmetic, register, integrate & mure denoise each channel/pannel

- combine SHO & RGB for each panel, DBE,

- slight SCNR and CT on hue channel

- Background neutralise

- match all SHO pannels bg with PixelMath, same for RGB

- Mosaic by Coordinates the SHO pannels

- Gradient merge the 4 SHO panels

- Extract the Ha channel for the mosaic, and used it as the Lum channel for the image

- Register (mosaic separate) the 4 RGB pannels against the SHO mosaic

- Gradient Merge the 4 GRB panels

- delinearize with HT the SHO and GRB images

- CB, CS, TGV, MSMT the SHO image

- Apply a & b color channels of the RGB image to the L channel of the SHO image under starnet++ mask

- Slight Erosion under starmask

- levels and slight color adjust in Mac Photo

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.
