Bubble Nebula, named NGC7635, a color IMG. Aug/Sep-2021, CPH, DK

A color image of the Bubble Nebula.

As the weather forecast look "ugly" in CPH, DK, I decided to process the frames already recorded.

The SW processing effort was divided into several tasks where two scopes and three cooled cameras were used.

Check image "C", the 2" Radian Triad Quad band filter exposure contribution & taken with the ZWO asi 294MC pro cool camera.

Check image "D", the 2" UV-IRcut filter exposure contribution & taken with the ZWO asi 294MC pro cool camera.

Check image "E", the PI starless feature was used (and a PS dust & scratch function) on a color image and it was blended in again as a lighten layer with a given opacity.

Check image "F", the 2" UV-IRcut, Ha & OIII filter exposure contribution & taken with the ZWO asi 294MM pro cool camera.

Check image "G", a refractor BW mix image. It's a Lum,SII,Ha,OIII filter exposure contribution & taken with the ZWO asi 1600MM cool camera.

Subs/frames was calibrated with darks & flats.

As usual it's taken in a light polluted area, Bortle 6 sky looking south, Bortle 7 sky the other directions/surroundings.

My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,
Red Zone
Kind regards Niels

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.
