M81

Well, I just got my hands on Fitswork 4 and have figured out how to use it, sort of. Its user interface is translated from German, so us english speaking folks are on our own to figure out how to use it without much documentation.

This image of M81 was taken from my backyard with some major light pollution gradient and looked wonderful behind a veil of terrible. I managed to figure out how to use Fitswork's pretty decent de-gradient tools enough to fix this image and remove the gradient veil to reveal this image! A had to do little bit of saturation pump up to bring out all those wonderful O-B associations in the outer arms and remove a slight residual green sky-glow cast that tipped the center region from yellow to green. No sharpening was applied. Pretty decent for 15 minutes in the backyard. I will have to get around to imaging this from a dark sky site one of these days under some really good seeing so I can try for bin 1.

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.
