This was actually my first time capturing M51/NGC 5194 and it's companion NGC 5195. I am pretty happy with how this picture turned out. in total I captured 52 x 240s subframes for a total of nearly 3.5 hours. I was quite happy to image again since it was cloudy the past few weeks-months.

I stacked and edited the picture in PixInSight:
- Graxpert
- SPCC
- DynamicCrop
- BXT
- NXT
- HistogramTransformation
- Mask via RangeMask (Galaxy and protect background and stars)
- Curves Transformation slight s-curve and saturation
- ColorSaturation to saturate the blues and reds a bit more.

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.
