M80 RB+synthG

I'm trying to collect as many Messier targets as possible from my location, so I had a go at this globular after a session on M99. M80 transits at a mere 14 deg altitude from my location giving +/- 2 hours imaging time when it's above my observatory wall.

Being low down in the horizon murk makes for challenging guiding and imaging, nevertheless I intended to collect 10x2mins each RGB, but lost the target after getting only R+B data.

I've not had any clear skies since 1 May and with astronomical twilight approaching fast, together with a growing Moon phase I decided to process the RG with synthetic G.

Only 9 of each RB were included after grading, for a total of just 36 mins final integration, so a very noisy background and hardly a prizewinner, but it's one more target towards my personal Messier collection.

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.
