NGC7822 - A star forming complex (Jérémie)

NGC7822 - A star forming complex

Testing the combo 71/347 with the Canon EOS Ra and the STC Duo Narrowband clip-in filter.

I was waiting for the L-Extreme or L-Enhance to be released as clip-in filter for the EOS R (to use that with my lenses), but it seems delayed for the time being (was supposed to be released on June, and learned they will only make the L-Pro for now). So I went for the STC, that has two 10nm narrowbands (Ha and Oiii).

And I am quite happy of the results : I am pretty sure that I can make some nice wide field pictures of our wonders during newt holidays, with darker skies - hopefully.

So here the second shot I made with this setup : NGC7822, another nice star factory.

Wikipedia says :

NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, the elephant trunks.

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.
