The Phantom of the Opera Nebula - SH2-173 Ha-RGB

The SH2-173 emission nebula can be found in the constellation Cassiopeia. Its distance is 8,800 light years, and it is located in the Perseus arm of the Milky Way. It is also known as the Phantom of the Opera Nebula, thanks to its similarity to the mask worn in the famous musical. It is a very faint nebula, so a long integration time is required. Baader's H-alpha Highspeed (f/2) Ultra Narrowband 3.5 nm (C-MOS optimized) filter also helped a lot in achieving this result. The RGB part of the photo was made with the Celestron HD Edge9.25 telescope and ASI2600 MC Pro camera using the Astronomik L2 UV/IR Block filter, while the Ha part was made with the Baader H-alpha Ultra-Highspeed filter and ASI1600MM Pro camera.

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.
