36min integral RGB exposure of Collinder 261 (Cr 261) open cluster, the nearby Alpha and Beta Mus stars and several dark nebulae, captured remotely using Telescope #5 (Officina Stellare Riccardi-Honders RH200 D = 200mm f/3, FLI Microline 16200) system of ChileScope observatory on Jan 1, 2023.

The Cr 261 is a thoroughly studied cluster [1-3], even in the recent years [4]:

A narrower FOV RGB exposure of the area centered on Collinder 261 cluster was obtained later with ChileScope T2 instrument under [5]:

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.
