126min integral LRGB exposure of Fornax (dSph) Dwarf galaxy [1] and its globular clusters [2, 3] - captured remotely using Telescope #5 (Officina Stellare Riccardi-Honders RH200 D = 200mm f/3, FLI Microline 16200) system of ChileScope observatory over 9 separate imaging sessions carried out on Feb 27, 28, 2022 and Mar 1, 2, 3, 4, 5, 6, 9, 2022.

Imaged exclusively in pre-dawn conditions, with 30% of frames acquired lost to satellite streaks going directly through the central part of the frame (18x out of 60x 180s frames lost due to that effect).

Title: Identifying 4 globular clusters in the Fornax Dwarf (For dSph galaxy) - B&W only using ChileScope T3

Description: 30min of R & G exposure of Fornax (dSph) Dwarf galaxy captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope observatory back to Oct 2020.

R & G exposures all merged into a single B&W image. Four of the globular clusters belonging to that galaxy are visible here [1].

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.
