The Lion Nebula (HOO) (HOO)

Revision title: HOO final

Just after shooting M101, the moon was really bright, it was then impossible to shoot in LRGB but the weather was perfect. I started to check, based on my position, if some nebulas were in my filed and indeed, I noticed the presence of a nebula that I didn't know, The Lion Nebula that is a very faint emission type nebula in the constellation Cepheus. This Nebula lies at around 10 000 to 12 000 light years. One Wolf-Rayet (RW) star is clearly identified here. On the bottom right, we can also noticed the presence of a small Planetary Nebula (PN G101.5-00.6).

I was really lucky because we had almost 2 weeks of perfect weather giving me the opportunity to shoot a lot even if the nights were very short. I guess that we cannot have everything. I hope that you will like my version.

For the sake of information, the two last nights with OIII filter were done with a ASI 2600MM instead a 1600MM. The gap in huge betwee those two cams.

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.
