M 63 taken a few weeks ago which I still needed to process.

I am pretty satisfied with the stars in this one again :-). Core is still a bit bright but will work on that in a updated version.

I also changed my guiding camera from the Lodestar X2 to the ZWO ASI 290mm mini. With the latter my guiding resolution has much improved. The Lodestar is better suited for OAG because of the bigger pixels. Not that I can see that much difference in the results though... Probably because my Mesu Mount 200 works so well.

In addition, I was also investigating capturing the blue light only near or around the meridian. And my thoughts are it could be helping indeed! The blue stars seems very good in this image, but I need more sessions to make it more definitive. The stars on the whole field looks very nicely blue now.

Only in 2 edges it goes a bit wrong, but that is because I have some small tilt in my configuration, I think. Will investigate that further with CCD Inspector.

This image finalizes my astronomy season in the Netherlands. Now we gave grey nights in the Netherlands for the coming months. But I will return to Morocco soon again... I was planning to be there next month again but that will be a month later probably.

Description: - increased saturation.
- ran SCNR again.
- canonbandingreduction script to reduce some errors (I always have a band in the top because of the extreme dithering I am doing... Will start making flats next season... But it seems that this script fixes it more or less).

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.
