M1 Crab Nebula Ha (Lum) + OSC

I finally got around to editing the OSC color version enhance with the Ha data with only 1 clear night to capture in the last 3 weeks. Data is somewhat limited and never could bring out detail and saturation at the same time. Still pretty noisy as well. Once again a lesson to be learned about being patient with C9.25 and getting more data and not impatiently moving onto the next target.

The crab nebula is a striking supernova remnant with the initial supernova being document in 1054. The supernova brightness could be seen for 23 days during the daytime and 654 nights. Named the crab nebula because it was thought to look like a crab in the 1840s.

The nebula is about 6,300 light years from earth and has been accurately measured to be 11x 13 light years. The nebula continues to expand at 1,800 km/second allowing astronomers to track the expansion over a 12 year period.

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.
