M 51 (NGC 5194 & 5195) with ILRT

This is a combination of already published images of last year (2018) with newly acquired ones taken this year (2019). I selected more carefully the RAW images for the image stacking laying emphasis on better SNR and lower FWHM of the stars.

By the way, the Intermediate-Luminosity Red Transient (ILRT) is also visible. Try to find it (or if not, have a look at my pictures of the ILRT: https://www.astrobin.com/405028/?nc=user).

D

Description: Simply better than the previous one ....But could also be changing on a daily basis as I am always unsure, how to deal best with the little details in the background, colour saturation etc. -

E

Description: more contrast...

F

Description: Reprocessed, cropped and made background better visible ("deeper")... It's hopefully an acceptable tradeoff between a too dark and too noisy background.

G

Description: Different color calibration (white reference is the integrated light of both galaxies).

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.
