M94 Croc or Cat Eye

Tight spirals with multiple layers make this an interesting structural galaxy if not the most beautiful artistically at least. You can see the star burst inner spiral with its bright blue stars shift towards dust and an outer ring of material. Interestingly enough, the less colorful ring is forming stars at a faster rate than the bright inner core region and the outer ring is likely a remnant of another galaxy collision on borrowed material from another galaxy. Even more mystery is around the lack of theorized dark matter holding this form in a stable pattern.

Processing:
Selective curve stretching was needed to make the outer ring more visible. Tricky to not pull the core up too much at the same time. I cross referenced other images and the color really does dramatically shift from the blues to the darker dust arms.

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.
