Balancing star colors near the Witch Head Nebula (Ewam)

Balancing star colors near the Witch Head Nebula

See that bright yellow star, SY Eri with blue companion, little above the center of this image? It's a variable star, ranging from 10.40 to 11.40 (photometric system p, so it says in Stelarium). General magnitude is 8.30.

The field clearly reveals stars 'till some 13.7 magnitude - further into dimness, it drowns more and more into the noise floor, where only my Stellarium can help me spot some 14th+ magnitude *rescapee*.

VERSION B : low res' crop around SY Eri, tweaking with the "LIVE" tools in astrotools : bringing extra diffraction on brighter stars. It does work nicely if not overdone...

As I've got to be patient till I can set up my mount, tomorrow, and try anti pollution filters, here I gave it a try at this field of stars around Cursa, in order to get the better possible color balance, without mount or filters, under my *near an highway's light pollution* sky.

These 15 frames are a 1/3 croped from the original. Shutter was at 1sec3.

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.
