The Lion Nebula in SHO

This is my longest project so far. The O3 and S2 signal was really faint, so I think I made a good decision with this long exposure, especially from my Bortle 8 zone. I had to throw 7h worth of subs due to clouds and guiding issues. I also added the RGB stars.

It is a faint emission nebula situated in Cepheus. It is located around 10000 ly away and it contains Wolf-Rayet stars, massive, evolved and luminous stars .

Acquisition from August 24 to September 13 :

Ha 143 x 300s

O3 130 x 300s

S2 112 x 300s

RGB 3 x 60 x 60 s

Total : 33,5 h.

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.
