BACKYARD SPACE in JOHNSTON: The Cygnus Wall

Posted

The Cygnus Wall is approximately 20 light years in length and known as a star forming region.

It’s an emission nebula in the constellation Cygnus close to Deneb, the brightest star of the Cygnus Constellation.

The North America Nebula resembles the continent of North America and, if you look closely, you can even make out the Gulf of Mexico.

The nebula lies roughly 2,590 light-years from Earth and stretches 90 light-years from North to South!

It also covers an area in the sky that more than 10 times the area of the full moon.

I took this Image over the course of two nights using my H-alpha and Oxygen-iii filters with my dedicated astrophotography camera.

I combined the two filters into and RGB image to create an HOO (H-alpha+ Oiii+ Oiii) image (the reds representing HA, and blues representing Oiii). I used an astronomical photo editing software to stack and bring out the details and nebulosity.

These images were captured from my backyard in Johnston.
