M63 - Sonyashnyk

The sunflower (sonyashnyk) is the national flower of Ukraine, a symbol of light in dark and troubled times - our hope and prayers are with her people.

M63 is an interesting galaxy in that it does not have clearly defined arms, rather it is a flocculent spiral, about 27 mLY away, spanning 100,000 LY.

A bright core with fine dust lanes, is surrounded by flocculation filled with young blue star clouds, and surrounded by an extended halo (just beginning to show in my image). A strange linear dust lane cuts across the left side of the disk.

I am pleased with the signal, given just under 4 hours, collected under a bright moon. A longer integration would improve the noise reduction, although dark skies are needed to show off the outer halo/ star streams which loop over the galaxy.

This image was photo-bombed by at least 12 satellite trails! I had difficulty removing these with SD stacking, and have tried to 'heal' these - I may have to remove the offending frames from the stack.

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.
