Here is another image that I did not get around to processing until today.
This image of NGC7023 is the Blue Iris Nebula. It is imbeded close to the area of the North American Nebula. This was taken on August 10 2021 with my Astro Tech 10" RC telescope and the Starlight Express Trius Pro 814 Camera with LRGB filters. '
This area of the Blue Iris is imbeded in a large ares of brownish gas and dust. The blue Iris is caused by the central star which is a blue hot star that illuminates the gas near it. The star is known as HD 200775, a B-type main-sequence star.
It is approximately 1,000 light-years away from Earth.
The star's high temperature gives it a blue color, indicating it is very hot.
HD 200775 is responsible for illuminating the surrounding reflection nebula.
It plays a significant role in the formation of the nebula's structure and features.
The star is part of the larger constellation of Cepheus.
