Sharpless 2-132, the Lion Nebula, is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon Cep, and has a size of about 40 arc minutes.

A uniqueness of this image is the intense starfield that it is in. A blanket of stars making this a difficult target to process.

It is estimated to be about 10,000 to 12,000 light years away from Earth, but this is no more than an estimate.

This image consists of 16 hours of exposure from a ZWO ASI071MC OSC camera using the OPT L-Enhance dual-band narrowband filter at -6c. Z73 440mm telescope. Image acquisition with APT, guiding with PHD2, and processed manually in PixInsight to a HOO type palette, sharpened and converted to jpg in Adobe.

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.
