M63 (NGC 5055) sunflower galaxy

80 minutes of integration brought out some detail in this galaxy, taken under clear, moonless skies, from 32 mLY. My autoguider kept my fork mount tracking accurately with total RMS 1.28". I focused using a bahtinov mask prior to the exposure, and can't decide whether this drifted during the cold early hours of the morning, or whether I just need more integration time, or whether it is the nature of this galaxy not to give up too much detail. I used a broadband Lumicon light pollution filter, and would like to try this with my narrow band filter to see if I can capture the HII regions that speckle this delicate spiral.

Description: Apart from an annoying artefact in the bright stars, I think this higher resolution image HDR processed in Penumbra v0.6 shows off the flocculation in this spiral quite well. I will try using Startools to mask out the bright stars to avoid artefacts in over exposed areas.

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.
