Comet C/2012 K1 (Pan-STARRS) in Ursa Major

A deep image of comet C/2012 K1 on 2nd/3rd May 2014. Imaged from dusk to dawn on a rare clear night

The faint ion tail is visible running down to the lower right.

Notes: All images were unguided on the 10 Micron mount which was set up and polar aligned to 15 arc second error during dusk. This took only 30 minutes and 3 passes of the model builder procedure (twilight lasts > 2 hours so I had plenty of time).

A full tutorial for the processing method is presented here

Imaging processing was the Bernard Hubl method with my own custom modifications. DSS was used for stacking with the star isolation and comet isolation using aggressive sigma-kappa (1.15/10) average combines.

Version B: Star size reduction and colour enhancement

Version C: Significantly reduced the star trails remnants by using a vertical banding noise reduction procedure.

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.
