C/2022 E3 (ZTF)

Taken 27 January 2023 at the OKCAC’s Cheddar Ranch Observatory. Half moon, temp 35F, humidity 69%, clear. Winds 15-20mph, partially blocked by the club building and my truck.

This was a 40 min session with my Vaonis Stellina. 240 10 sec frames, auto stacked. No post processing.

Some of what looks like the tail is actually the comet moving through the frames. But I think it gives it a nice effect.

The Stellina does not have comets or asteroids in it’s catalog, so I got the RA and Dec from Sky Safari and entered them manually. I was disappointed the comet wasn’t centered, but I don’t know how to adjust that yet with Stellina.

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.
