Messier 63 The Sunflower Galaxy

Messier 63 is a flocculent spiral galaxy where the spiral arms are patchy, rather than continuous. Thus the galaxy has discontinuous regions of star formation stretched into spiral patterns by the galaxy's differential rotation. M63 is about 30 million light years from us, a part of the M51 group, and is about the size of our own galaxy.

This image stack was processed with 2x drizzle, and then the final image was developed with an LLRGB type protocol.

Description: Here is the same image processed in Startools and a little in photoshop. While I am still on the learning curve, I am impressed with the control of the image, particularly the dynamic range, detail and color. A part of the learning curve as well, is that this enables me to see all the defects in my data, and to thus learn how to improve my acquistions.

Description: While I was happy with the detail, this image had a blue cast, and galaxy colors were not quite right. Also, I was missing a lot in the fainter outer regions that I wanted to pull out of the background. And with more Startools experience behind me, I thought I could do better. Hopefully I did.

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.
