M 63 - Sunflower Galaxy

Decided on imaging the Sunflower galaxy instead of Sombrero mainly because the few clear nights we have had, happened to line up with quarter moon right next to Sombrero. It ended up being a very good selection, with almost perfect orientation to show off its beautiful spiral arms and dust lanes!

This is from only two night's of imaging, while dodging cloudy nights and rain. The features of this galaxy begs for a few more nights of imaging to pull out more of the prominent dust lanes right up front.

While it's still up, I'm hoping the weather cooperates so that I can get more time on it. Will post updates as revisions.

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.
