Spaghetti Nebula HOO Rokinon 135 mnm ( Sh2-240, Simeis 147)

This was a fun challenge to see what the Rokinon 135 mm could do with near full moon setting. I had originally planned on using 2x2 bin (4.63um) Ha and O3 and then using 1x1 Ha as a lum layer; however, my 2x2 Ha data was defeated by cloud cover. So, I used the 1x1 one for the Ha, lacking on the SNR, I probably pushed the data too far. Next time I have some clear nights with 135 mm, I plan to add the 2x2 Ha to see if I can bring out a better Ha layer in the image.

The Spaghetti Nebula is a large super nova remnant from approximately 40,000 years ago. Its larger angular size at 3 degrees and low surface brightness make it a challenge to capture. Located 3000 light years from earth between the Constellations of Auriga and Taurus.

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.
