Now That's a Comet...C/2023 P1 Nishimura Sept 7, 2023

Centered at 04:49am, Comet Nishimura has just cleared the trees on the mountain ridge. Although only 4 degrees off the imaginary 0 degrees horizon it was spectacular to watch a thin spike like tail rise first (before the comet's central condensation) on the computer screen. I continued to take 30 second sub frames and managed to stack 37 x30 secs before the morning twilight ruined the rest. The comet had a max altitude of 9.5 degrees when I finished shooting. Last quarter moon was also present to make things challenging. But the exceptionally clear transparent morning made imaging better than expected in the Mountain thin air. Star sizes of course were bloated due to the atmospheric dispersion.

The comet and much of its tail were readily viewable in a pair of 18x 50s image Stabilizing binos, with its tail extending upward in most of the binocular field of view.

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.
