NGC1491 - Fossil Footprint Nebula

What a challenge, this target is a beast! I wanted to dedicate this image to my second cousin, an amateur paleontologist, who passed away last year at the age of 79.

That being the case, I collected 79 hours of data for this target and STILL, the outer regions were very faint. My mount doesn't behave well for longer exposures than 5 minutes. Clouds and full moons didn't cooperate a whole lot either.

I started shooting September 2nd, and collected until October 16th. Then I processed it about a dozen times. This is my best to date, but I reserve the right to try again over the winter.

Thanks for looking!

Description: I reprocessed this with the new Pixinsight PSF weight option, and a totally different workflow. I was able to reduce pixelation in the outer regions and keep detail, or maybe get some more detail, out of the core area.

Description: Tried to tamp down some splotchyness in the background. Splochiness?

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.
