M60 + NGC4647 + SN2022hrs

My second supernova in a Messier object.
This time I tried to measure the magnitude in the stacked linear image using PI AperturePhotometry. I used the flux data and calculated the magnitude using the equation mag1 = mag - 2.5*log10(flux1/flux2) where mag1 and flux1 are the data of the supernova, while mag2 and flux2 are the values of the referenec stars. PI found 11 reference stars. The results of the evaluation are:
Cmag   12.5 +/- 0.6
Rmag   12.4 +/- 0.3
Bmag   13.3 +/- 0.5
Vmag   12.7 +/- 0.5
Jmag   11.5 +/- 0.5
Hmag   11.2 +/- 0.6
Kmag   11.1 +/- 0.7

With ASTAP I measured 12.5-12.7 mag

Maybe I can take additional photos during the following nights to measure the brightness decrease.

Description: I used NoiseXTerminator from RC Astro for the first time and I'm impressed by the results. Never got that good results in my own trials with a combination of TGV and MLT/MMT

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.
