NGC281, the Pacman Nebula

Sep2017 data was 7x900sec on a Canon6D through an f/4 AT8IN, fl=0.8m.
Jan2023 data was 20x180sec on a 1600MM with Astrodon 3nm Ha through a 0.25m f/3.8 newtonian, fl=~1.1m (Ha data is here).

Will update acquisition details as I learn; I'm very new to combining old + new data, as well as differing focal lengths.

I'm leaving "nasty" gradients for now because this image is, for me, a representation of my journey. I'm excited.

Title: (revisiting subs 4.5 years later)

Description: I tried to reprocess the data nearly five years after my first attempt. It's very reassuring to find that I'm learning much more than I sometimes assume of myself.

APP: Heavy LPC & CBG (significant amp glow from Canon6D), CSC.

Title: (working in new Ha data 4.5yrs later)

Description: My first attempt at insetting data from my current scope with that of past GSO scopes. Leaving obvious gradients for now; happy at contemplating both how far I've come and have to go.

APP: Use original stack, mosaic with new Ha data (30x180s), heavy LPC & CBG, CSC, crop.

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.
