Stars of Cygnus

[Knight of Clear Skies]

Back in December, I was at a loss what to image, so I simply pointed my camera towards the Milky Way and let it run. I could see a bit of nebulosity and some dark nebulae in the framing shots.

Turns out the brightest nebula is the Tulip. There are some subtle lines of Ha which tend to frame the dark nebulae. Looking at deeper images I think these are shock fronts of ancient supernovae, which swept materiel into the dark regions.

Samyang 135mm @ f2 and modded 100D, 34 minutes of data in 2 minute subs.

Here's a wider view of the region, the imaged area is at top-right.

Nice work with a modded 100D.  I have one and get a fair bit of noise which is difficult to control (especially green).  Did you use darks and/or dithering?

Thanks. No darks but I'm imaging without guiding, so the target moves a little across the sensor on a run.

Thanks for the info.  I might try a few stacks without darks to see the difference.

Was this done on the Star Adventurer?

Yes, this was using the Star Adventurer, it's happy with the weight of the 135mm Samyang as long as I balance it a touch east-heavy.

Lovely - lots going on in that part of the sky!
 

Glad I’m not the only one whose dithering comprises simply dodgy tracking!
