Late to Leonard's party

Despite another mediocre forecast, the skies cleared a little on Jan 1 around 10pm. I rushed out with my portable rig to a location where my horizon isn't obscured by trees and had a go at imaging comet Leonard.

Not having imaged for a month, I did lots of dumb things - forgetting to cool the sensor was the dumbest - and with the weather, I wasn't able to get a decent flat field. In the end I only got 30 x 30sec frames through cloud in twilight and looking towards the lights of Queenstown, but the Nikon is a fact lens and I am happy with the results (actually amazed, given the conditions and my impcompetence).

Initially I worried about the reddish blotches, thinking it was the flat-field. But after referring to Telescopius, I am pretty sure this is diffuse nebular emission. [This Nikon is fast for low surface brightness stuff. ]

While it isn't anywhere close to some of the spectacular images of Comet Leonard on this site, this image does show almost 7degrees of tail. And, hey, I am imaging again from Speargrass Flat.

Description: Tried to bring the colours in Leonard's head a little more, while suppressing the diffuse nebular background.

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.
