Sadr Region, Cygnus

I don't often like completely starless nebula astrophotos, but this one fairly screamed "oil painting" at me when I saw the brown and gold tones.

SkyWatcher Quattro 8", 4hr10 data, IDAS NBZ HOO filter, reprocessed from last year using PI and a modified HaHOO palette.

What if I tell you about a galaxy that has not one but two supermassive black holes? What if I tell you that these SMBH orbit very close to each other, at a distance of about 0.07 l-y? And, would you believe me if I tell you that these two, at the center of this galaxy, emanate a relativistic jet producing an active galactic nucleus? This all happens at the center of this well-known galaxy: M81.

M81 is the main galaxy of a group formed by about 34 galaxies. Although it is photographed a lot, I have noticed that in most of the pictures, our galaxy shares credits with M82, a close galaxy it is interacting with. I find, however, proper to take a picture of this galaxy by itself. Did my best to get as much detail as I could and took care to also show an irregular galaxy that turned out to be a satellite of M81: Holmberg IX. You can find this irregular and faint fuzzy at the north of M81. The small pinkish features on the arms of our galaxy are indeed emission nebulae, in which stars are being born.

So to continue on my previous post talking about auroral mist, this is a prime example of a quality mist like view from my camera. While most of the aurora shots you see are very bright, visible to the naked eye, these type of images are the aftermath of such storms. The energy that was brought into the earths magnetic field is dispersed, and creates a much duller to the earthly observer aurora. But with the magic of a good camera and a proper lens, we are able to capture the hidden beauty of these mist like states.

This was shot on my back porch north of Fairbanks Alaska a few months ago after a very intense substorm.
Settings were 8” exposure, 2500iso, f1.8 20mm lens.
