NGC 7822: A Cosmic Nursery of Stellar Creation
Prepare to be mesmerized by NGC 7822, also cataloged as Sharpless 171. This celestial spectacle is a dynamic and highly active region where stars are born, showcasing some of the most awe-inspiring formations in the universe.
A Glimpse into Stellar Birth
NGC 7822 is a vast stellar nursery, approximately 3,000 light-years away from Earth and spanning an impressive 150 light-years across. Its dramatic appearance is characterized by the presence of magnificent "Pillars of Creation" and intricate "elephant's trunk"-like structures, all sculpted by the powerful forces of stellar winds and radiation from massive, young stars within the region.
The Astrophotographer's Journey
Capturing this celestial gem was a testament to dedicated astrophotography, even under challenging conditions. The image was brought to life using the following equipment and techniques:
- Telescope: RedCat 51 WIFD
- Filter: L-Ultimate 2” filter
- Camera: ASI 533MC Pro
- Mount: ZWO AM3 Mount
- Autoguiding: ASIAIR Plus with 120mm camera and 30mm guide scope
Acquisition Details:
- Light Frames: 53 frames at 300 seconds each
- Flat Frames: 25 frames
- Bias Frames: 20 frames
Despite imaging from a Bortle 5 location with a 90% moon in the sky, the dedication to capturing these valuable data points allowed for the creation of this stunning image. It's a powerful reminder that with the right approach and persistence, incredible cosmic vistas can be unveiled even from light-polluted environments.
Clear skies!
