Messier 51 over two years

Intro:

The image you are seeing right now is a little bit over 20 hours of exposition, over two years. Every single image was taken in my backyard, under an average sky and a bortle 7. Because the sky was not that good, I had to trash a lot of images and shoot under the rare moonless nights. Since I started about 3 years ago, this image is one of the biggest projects and accomplishments I have ever done in astrophotography.Equipment used (over two years):Telescope: Celestron Edge HD 8” @ F/7Mount: Sky-Watcher EQ6-R ProImaging cameras: ZWO ASI294MM Pro & ZWO ASI2600MMFilters: Baader HaLRGB CMOS Optimized 31mm & Antlia Ha 3nm Pro 31mmGuiding system: Celestron Off-Axis GuiderGuiding camera: ZWO ASI174MM MiniAcquisition software: ASIair PlusOthers: 3D printed Spikes for the Edge HD 8”(Pre)Processing softwares: AstroPixelProcessor, PixInsight & PhotoShopObject description:

The Whirlpool Galaxy, or M51, is a stunning spiral galaxy located 23 million light-years away in the Canes Venatici constellation. It is known for its swirling spiral arms and interaction with the companion galaxy NGC 5195, resulting in intense star formation. M51 offers valuable insights into galactic dynamics and serves as a captivating target for astronomers.

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.
