Gamma Cygni (Sadr)

Gamma-Cygni-Sadr-regionCutting through the Milky Way, the constellation of Cygnus is home to some of the best sights in the night sky; the North America Nebula, the Dumbell nebula and another one I plan on tackling soon, the Vail nebula.

At the heart of the constellation, bright star Gamma Cygni (Sadr) is surrounded by nebulosity. I first captured this a couple of years ago – a shot which made me realise the potential of a simple DSLR and barn door tracker. I felt it was high time I revisited this old favourite with the 180mm lens.

The butterfly nebula sits to the left of Sadr, with some good structure visible. The intricate bubble-like structure of the crescent nebula can be seen (lower right) amid the vast sea of stars which make up the Milky Way.

Image details: Nikon D7000Nikkor 180mm f2.8 at f2.8. 56 minutes (112 x 30 seconds) at iso 800 using didymium filter. Stacked with Deep Sky Stacker and tracked with barn door tracker.

    I love your web and all your images. You explain very well the technical details of every photo (ISO, f stop, number of subs…) but I would like something about your post processing.

      Hi Pedro – glad you like the site. I always do the post-processing in Photoshop, but you’re right, I haven’t got much info about this on the site. I’ve just started putting a page together to document all different techniques and tools I use for processing the images. I’m aiming to have it up in the next week or so, so keep checking back as it should be up soon! Cheers… Nick
