C/144P/Kushida - 'bullseye'

Like a tiny arrow, this short period comet is aimed at Aldabaran, the bulls eye. Sailing into view since my last image, the comet was discovered in 1994, and has an orbit of around 7.5 years.

It has been a real pain to process, with traditional approaches based on combining starless (registered on the comet) blended with the star field proving very difficult, due to the tiny scale and limited integration. Eventually I gave up and you are left with an image showing the green coma of the comet and another coma 1.25 hours later.

Anyway it is not worth spending more time on, but it was fun to see it barrelling towards Aldebaran.

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.
