Steve and I began this collaboration on the 1st February when I captured the first RGB subs, then we have haltingly acquired the data whenever conditions allowed: Steve the Luminance and Ha, me the RGB, all binned 1 x 1. It was important to capture all the data during the best seeing - not the best winter for that as we all know - however, especially the RGB at the maximum altitude too, which meant much later in the evening, often when Devon was clouding out. So it wasn't until Saturday 2nd April that I could finally capture the last few RGB subs having discarded one hour of each for poor seeing. Steve had a slow start with poor weather but had a burst of speed towards the end of March with a few clear nights on the trot. It was exciting sharing the calibrated data - and we were both delighted to see the results.

Messier 63 has relatively low surface brightness and has recently shown some interesting tidal and halo features - need big scope and dark skies to reveal these. We are both very pleased to have captured the distinctive clumpy texture and rich colouring. Processing required delicate treatment for some elements and some brutish welly for others to help coax the subject out from the background. Details: Scopes & CCDs - SW Esprit 120mm with QSI690 and WO FLT132 with QSI683 both at F7 Mounts - Mesu 200 and 10 Micron GM1000HPS Filters - Astrodon Software - we both use the magnificent SGP, PI and PS Data - 36 x 600s Lum; 16 x 60s Lum; 11 x 1200s Ha; 13 x 600s each R, G and B. Total integration a shade over 16hrs.

This is my processed version, completely done in PI.

Thank you once again to Steve for good humour, patience, a sense of wonder and fun.

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.
