Messier 63 - the Sunflower Galaxy

I finally tried M63! It was a bit a panic target for me because of all the fine details in the galaxy disk and knowing that my mount might not guide good enough - what it didn't. However, after some crude initial guiding issues it started to work okay(ish). The average RMS of 0.65-0.85 arcsec was still more than twice than it would be good for my camera and scope combo - but in the end I was glad that I tried. I lost about 1.5 hrs of data due to the technical issues and guiding deviation but to be fair, I only have a CEM25P which is really working at its very limits when carrying my EHD8.

However, this is only 3 hours captured at F10! So, in my opinion it turned out quite nice and even a fair amount of the tidal halo is visible - I did not expected that.

Description: I added about 1.5 hours of data and processed the imiage completely new. I calibrated in APP but stacked and processed in PixInsight this time. Finishing as usual in Photoshop. In my opinion a better balanced result :-)

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.
