The Sky on Fire, Mosaic of the central Cygnus
A three panel mosaic in visual palette, combined from narrowband channels, shows a three degrees patch of the central Cygnus gas formations. I have published a mapped color version few days ago, it can be seen HERE.

Astro Anarchy, the year 2016
HAPPY NEW YEAR
This post is about all of my astronomical photos from the Autumn season of the year 2016
All my photos from the Spring and Autumn seasons of 2016 are taken with my new imaging setup. Celestron Edge HD 1100 with 0.7 reducer at 10-micron mount. Apogee Alta U16 camera with Astrodon filters and an active optics unit, SXV AO LF, from Starlight Xpress.
My humble thanks to the supporters, they made my work possible!

Bright nebulae of the central Cygnus, a seven panel mosaic
My last photo for the year 2016 is a seven panel mosaic of the central Cygnus. I shot last panels for this mosaic at 30.12. 2016.

Bright nebulae of the central Cygnus
I had about six hours of clear sky at night between 23.- 24.12. That was just enough to shoot this relatively bright emission area in constellation Cygnus.
