M53 and NGC5053

Globular clusters are usually my 'thing' but I couldn't let a clear bank holiday weekend go without imaging something even if the moon, horizon,and lack of accessible bright narrow-band objects made target selection a little tricky. The combination of M53 and NGC5053 fit my field of view quite nicely and I could get a decent amount of time before they wander too close to a streetlight. It also gave me an opportunity to see if I could improve my flats with some neutral density film to extend the length of the exposures with broadband (no electronic shutter in the QHY9!). I have one of the new Pegasus panels on order so I'm hoping that good 5 second plus flats for each filter and binning should become much easier

Rather shorter subs than I usually take but the moon and a little haze made me a bit cautious. The guiding wasn't that great but with shorter subs I wasn't going to lose any sleep about it!

Description: Long summer evenings = not much going on...
However I now have a dual Xeon workstation for home-office work so set up APP on it after trying a new SGPro beta with the Flatmaster. Way faster than a laptop and the better screen makes judging the image colour and quality much easier. The old version of this looks very muddy compared to this newer one even with minimal work!
It's still probably at least another month before it's worth setting up for any new data though... :-(

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.
