Sh2-132

The Sh2-132 Lion Nebula is a weak emission nebula in the constellation Cepheus. 10,000 to 12,000 light-years from us and over 250 light-years in size,
The main components of this emission nebula are hydrogen and oxygen, which are excited to high-energy states by ultraviolet light from nearby stars and then re-emit the light signal. The dimmer regions are "dark nebulae," which are clouds of dust that block light.

This work is the longest shooting time since the jungler, and the total cumulative time has reached nearly 38 hours. Why did it take so long to shoot, because it is too dark, and the S channel can hardly see any nebula details without pulling a single shot. It is estimated that it is also due to the darkness, and fewer people have photographed this celestial object. It started in April and ended officially in August, during which there were countless waste films and countless nights.
In fact, I didn't expect to complete this goal in early August. This month is the best golden time to shoot the Lion Nebula. It can be shot all night. Students who want to shoot can try it.

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.
