Collinder 411 - the southernmost Collinder object

This open cluster, if it can be called cluster, was listed by Melotte in 1915, actually is Melotte 227, also by Trumpler in 1930 and Collinder in 1931. It has 29 stars, and is wide open, actually stars 1 to 4 are not in the image, are close to the left hand side border. Also 24 and 25 are just below the inferior border of the image.
There are 4 galaxies in the image but only ESO 25-19 can be seen clearly, quite faint and small near the centre of the image. The other ones you can identify only looking at the same time the Simbad image or just thanks to plate solving annotations.
There are not many mentions of the cluster in the literature but it has nice stars, a bit far apart but nice anyway.
In the image also are CC and CE Octants, stars 11 and 14 of the cluster respectively.

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.
