Messier 70 (NGC 6681)

I have observed this object twice. The first observation was on 21 September 2014 at the Okie-Tex Star Party using a 12” Skywatcher Dobsonian: Seems to have a distinct core. Not very large.

The second observation was on 13 September 2015 at the Okie-Tex Star Party using a 12” Skywatcher Dobsonian: Class V Globular Cluster that is smaller and fainter than M69. It has a bright core and appears to be well concentrated. No individual stars discernible.

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

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.
