NGC5466 Globular Cluster

There's not a huge amount worth imaging with just a couple of hours of something approaching proper darkness - so another globular cluster it is!

I find myself asking how dark is dark enough? If I wait until the mean values settle then I'd be collecting very little data indeed and may as well give it up as a bad job until August

NGC5466 apparently has a claim to fame in that it has one of the lowest metallicities of any of the globular clusters, making it one of the oldest.

It's not particularly big, so despite not having too many luminance subs I drizzled this one and resized afterwards which gave less blocky looking star shapes. Down-side to this is keeping some subs I'd otherwise have thrown out to keep the statistics. It seemed to work OK anyhow. I got some subs the previous night as well with 2x2 RGB that were very unsatisfying so I collected 1x1 for everything this time around.

Description: After a full night sleep I reprocessed this one to see if I could make it look a bit more interesting with some more colour contrast and drop the sky background noise a bit more. It still looks like a glob - shock horror! I left this one at full resolution but saved as jpg to cut the filesize down.

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.
