NGC 1851

I have not observed this object. I obtained the calibrated light 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.

NGC 1851 has the highest surface brightness of all the Milky Way Globular Clusters. It is a relatively large and massive GC. The cluster is in a highly eccentric orbit around the core of the Milky Way with an eccentricity of about 0.7. (An eccentricity of 0 is circular.)

Shapley Sawyer Classification: II
Distance: 39,470 LY
Type: Far Halo Globular
Position w.r.t. core of galaxy: Below the disc of the MY on the sun side of the core.
Any stars resolved: N/A
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.
