M63 - A Sunflower in Space

M63, otherwise known as NGC 5055 and sometimes called the Sunflower Galaxy is in Canes Venatici at about 29 million light years from earth (though other measurements put it closer). it is about 12' wide and quite dim. It is a spiral galaxy but without clear arms visible.

This image is in visible light but with Hydrogen Alpha added into the red channel. It is a result of images shot from my backyard in February and March 2022. I also decided during this set to change broadband from gain 0 to gain 100, so there is a mixture here as follows (total 42.5 hours).

I welcome criticism and suggestions.

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.
