Comet 46P/Wirtanen, Pleiades, and Aldebaran on 12/16/2018

I was able to image Comet 46P/Wirtanen on the night of closest approach to Earth through a few lucky breaks in the clouds. The comet appeared close to the Pleiades (M45) and bright star Aldebaran on this night. I really liked the contrast between the green comet, blue-ish Pleiades, and the red giant star. I only wish I had more time to gather data this night before the clouds shut the fun down...

Imaged with a Nikon D750, 24-120 mm Nikor lens at 100 and 120 mm/F4/ISO800, 30s and 60 s exposures. Stacked using DSS for a total integration time of 15 minutes (subtracted darks, bias, and flats). Processed in Pixinsight: Cropped, gradient removal with DBE, Background Neutralization, Color Calibration, stretched using Histogram Transformation Tool, Curves Transformation, HDR Multiscale Transform, and ACDNR noise reduction.

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.
