Messier 51: A Case of Good Seeing Under the Aurorae

Revision title: LHE

This image contains what is probably some of the best seeing I've ever imaged under. FWHM at zenith over 1 second averages showed 0.8 to 1.2"

Somehow it seems I dodged all the aurorae raging across the sky last night, and have produced an image I'm very happy with.

Unfortunately there are some abberations- hot pixels towards the core that will not calibrate out.

Please note- this image also uses a much more liberal amount of blurXterminator vs all of my other images, most of the detail shown is barely sharpened.

Infrared data reveals redshifted background galaxies.

Title: NIR Luminance

Description: Suprisingly, this time around the NIR was the underdog for the seeing performance. I had to use a lot of BXT sharpening to get it to match up, and even then, the NIR stars are larger than the Quadband's.

Plenty of Redshift deep field galaxies available.

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.
