M63 Sunflower Galaxy

M63 taken from my backyard with Vixen R200SS. I carefully stretched the image using a combination of HistoTrans and ArcsinhStretch to avoid the pink burning of the star cores. Stretching was done in several steps (7-8). This helped to work out the fine details.

The colour saturation was increased with Saturation in CurvesTransformation. This came out with a quite yellow looking galaxy with no signs of the blue stars in the outer parts

Description: In the later version I slightly stretched the blue channel in CurvesTransformation. Then I increased the saturation using chrominance instead of saturation. This helped to work out the blue young stars at the edge of the galaxy.
I hope you like it
Clear skies!

Description: Newly processed with improved DBE, better fitting galaxy masks and less noise reduction in the linear state. This preserved many of the fine structures in the galaxy. I enhanced the blue stars by ChannelExtraction, stretching the blue channel with CurvesTransformation and finally recombination to RGB with ChannelCombination.
Still learning PixInsight ...

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.
