Resembling the shape of a medieval Sorcerer in the constellation Cepheus the open cluster NGC 7380 and the surrounding Nebula known as “The Wizard Nebula” otherwise known as Sh2-142 lies at a distance of approximately 8500 light years and spans 20 light years.
Captured recently using the new QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on the Takahashi 130 FSQ that we have the honor of testing for QHYCCD.
This new setup is available immediately for people wanting to subscribe to Grand Mesa Observatory's system 1.
https://grandmesaobservatory.com/equipmentIn this Hubble Palette version (SHO) the H-Alpha is mapped to green, SII is mapped to red and OIII is mapped to the blue channel. while the colors in this image are not the true colors, the narrowband filters used in the making of this Hubble Palette image reveal much more of the hidden gasses not visible in a broadband image, I used Starnet in Pixinsight to make the image Starless and then added the more natural star color by inserting stars from the RGB image. Captured over 4 nights in October 2020 for a total acquisition time of 11.6 hours.
