Messier 107 (NGC 6171)

Visual observation made on 14 September 2015 with a Skywatcher 12” Dobsonian: This is a faint Class X cluster. It has a large halo with a small core. Readily found with Telrad.

Visual observation made on 8 September 2023 with a 22" Obsession UC Dobsonian: M107 is not very concentrated. It appears to have a large dim halo and it does concentrate towards the center, but it remains diffuse. It does not look very spherical. No colors noted. No stars resolved.

I obtained the calibrated lights frames used to create the final image from Telescope Live. The frames were imaged by the CHI-1-CCD Telescope at the El Sauce Observatory.

Note: 80 LY in diameter.

Shapley Sawyer Classification: X
Distance: 20,877 LY
Type: Hub Globular
Position w.r.t. core of galaxy: Above the disc and on the sun side of the core. It is closer to the core than the sun.
Any stars resolved: No
Undergoing Core Collapse: No

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.
