Exploring Cygnus – Part 3

The final stop in our journey through the constellation of Cygnus the Swan takes us to the Sadr Region. The Sadr Region is a diffuse emission nebula surrounding the super giant star Sadr which is located at the center of the Cygnus Cross (also referred to as the Northern Cross). This nebulous region includes popular targets such as the Butterfly Nebula (IC 1318), included in this image, and the Crescent Nebula (NGC 6888 already explored in this series). It contains webs of dark nebulae to compliment the diffuse emissions. As a trivia, Sadr is about 150 times the radius of the Sun and has a mass of 12 times that of the sun. That’s big!!! Stay tuned for the next part of the journey and remember to look up and experience an amazing Universe!

This image is comprised of 3 hours of data using the Altair quadband filter (used for Oiii and Hb) and 3 hours with the SVbony Ha (7nm) filter; a total integration of 6 hours. Combination HaOHb.

Gear: Altair Hypercam 26c, Evostar 72ED, Askar 0.8 reducer, EXOS 2GT mount. Guided with SVbony 120mm scope.

Software: Phd, SharpCap, AstroPixelProcessor, PixInsight, Photoshop, Topaz Denoise.

  1. Always amazing!😃👍. There’s an awful lot of good stuff in the sky this time of year. I think a little bit later on you also have lots of good stuff in “The Scorpion’s Tail”. Anyway a very nice shot of the Butterfly. Plenty of good detail and texture and yes I do kind of like the color balance and scheme of this, I realize it can be manipulated to any colors you wish but I do find these pleasing. On the image as you posted it it looks like there is also a double star to the left of Sadr. (Unless that is just a coincidental asterism). Anyhow my good old 6 inch f8 Newtonian was quite good at splitting double stars and I enjoyed resolving quite close pairs.
    I think most of those I recorded in my observing logs.
    Looking forward to whatever your next series of pictures will be! Take care and by the way happy Solstice to you!!
