M 68 (NGC 4590) Globular Cluster in Hydra

Messier 68 (also known as NGC 4590) is a globular cluster found in the east south-east of Hydra and is about 33,600 light-years away from Earth. It has a highly eccentric orbit that takes it up to 100,000 light years from the galactic center and is one of the most metal-poor globular clusters in our galaxy and may be undergoing core-collapse as it displays signs of being in rotation. The cluster may have been acquired by the Milky Way from a satellite galaxy. It has an apparant magnitude of 7.3 and is about 11 arminutes across.
PGC42334 sits to the left and there are 5 more PGC Galaxies in the background.

What I could salvage from last night was added to last April's subs and improved with new techniques and tools in Pixinsight and offers a comparison to the object I imaged last night with the Red Cat 71's 4 degree FOV. Of course more data would help the Red Cat but dollar for dollar the Red Cat shapes up very well against the 127is and has none of the 127's annoyinng reflection problems caused by Televue not keeping the extra objectives anti-relection coatings up to date to handle modern CCD and CMOS chips that throw back a lot more light than film ever could.
On the plus side the optics are superb (as they should be at that price!). These days if I want a CDK 24 on a mountain in Chile that could be entirely rentable but where would be the fun in that?

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.
