The plan was to gather more subs for this over the summer, unfortunately the 314 has packed in. It's had a good run.

One of my favourite galaxies up there. I keep trying this one to hopefully get a wall hanger one day. With my LP it will need a lot more subs to lift the faint spiral arms away from the noisy background. The final image is a blend, of the under processed image and one that's over the top. Hopefully I'll be able to add to this during the summer months.

Description: The over processed version. One of Elon's satellites re-appeared after running DBE in PI. The stacking had removed it. I'll remove it for any later iterations.

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.
