Old data, new processing. Drizzle integration of 12 images at F:4

I spent the past year delving deeply into narrow regions centered on each of the goodies in this image. So nice to see an overview of all my old friends...

-------------

Rev B -- a more careful rendering, going all the way back to image stack calibration. All images were flattened with a 4th order surface prior to registration and drizzle integration.

The image represents a hybrid between the resulting stacked image and one with field stars diminished. By adding some of the original star-ful image to the star-reduced image, we ameliorate some of the effect of the star reduction fuzzing, while still showing good features in the underlying nebulae.

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.
