Description

The constellation of Cepheus is literally bathed in Milky Way dust structures. Near the center of the frame is the popular Iris Nebula. I admit that it is barely recognizable when you step back this far. The bright blue stars are some of the main visual stars of Cepheus.

I was finally able to get out from underneath a light dome and shoot some wide and fast exposures in sky measuring 21.7 SQM. The astrophotography, well, was definitely like nothing like I am used to! I've never even travelled with any of my equipment before. It was a whole new experience, mostly plagued by rookie mistakes. I also had to tend to a dew problem that actually led to a nice diffusion effect on the bright stars. I decided to leave those frames in the stack because I rather liked the wash-of-color appearance.

But, the simplest rig I could muster gave the best result. This includes a Canon 6D with a Rokinon 135mm at f/2 on a Celestron AVX mount. It was shot with an intervalometer cable release and centered using the mount's hand controller.

+1 for simplifying your life.
