Gamma Cygni Nebula (Sadr Region)

Gamma Cygni Nebula (Sadr Region)

 

The Gamma Cygni Nebula, also known as the Sadr Region or IC 1318, is a diffuse emission nebula that can be seen around Sadr (Gamma Cygni), the star at the center of the Northern Cross, which marks the heart of Cygnus, the Swan. Despite the name, the star and the nebula are unrelated. Even though it looks embedded in the nebulosity, Sadr is approximately 1,800 light years distant, while the nebula is much further away, at 4,900 light years.

 

After hearing a lot of good thing about the AZ GTI, I decided to get one and see what could happen. At first, it was really weird compared to the Star Adventurer. I took me multiple nights (almost 10) to get this picture. Flexure, Star Trails, Dithering issues and many more, but after that pain, the result was for me really nice. It allows me to make 5 min exposures, and to dither on the 2 axis (Goodbye Walking noise)

 

Now that everything is configure, I can setup the entire rig, in less than 20 minutes. And I'm now able to shoot mosaics, pictures coming soon :)

 

This picture was shoot during a waxing gibbous moon.
