Beautiful shot by @brandon_erdman_photography
Stars and sprouts surround one of my favorite old barns just before it was sadly taken down and burnt. Once a common sight, it’s now becoming more difficult to find these beautiful old barns as they age and fall.
98% illuminated Waxing Gibbous from last weekend. Have been travelling on work and haven't processed a few shots or taken any new ones this week. Hopefully the skies are clear this weekend. :)

THE MILKY WAY AND THE GOBLINS
During my recent expedition to Utah, I visited Goblin Valley State Park (an International Dark Sky Designated Park). Access at night is limited to pre-arranged groups and campers who are staying in the park.
The main attraction for nightscape photographers seeking an interesting foreground for a starry sky image are the Goblins. These are hoodoo like structures left from eons of erosion, forming shapes that some liken to goblins - hence the name.
This photo is a panorama made by putting a camera on a perfectly level tripod (no sky tracker), and rotating the camera horizontally about it’s vertical axis with overlap between exposures. The images are then stitched together in software which overlays adjacent images aligning those areas with identical stars and foreground features. The goblins were lit with two very low level LED flood lights placed behind and on either side of the camera. The light from these LEDs was so faint it could not be seen with the dark-adapted eye, but provided a useful exposure to the camera.
The sky did exhibit a lot of airglow, making it green and magenta in places that are normally black on a moonless night. This is common in photos made in dark places. In fact, there were waves of airglow regions marching across the sky clearly exhibited in the time-lapse I made with my second camera set up - this phenomenon is a form of gravity waves (not the astronomical kind) - another post for another day.
The details of the make up of the image are: Camera: Nikon D810 set to ISO 6400, Lens: Sigma 35mm F1.4 Art lens set to F1.8, exposures: 5 panels in portrait mode each having 1 exposure of 8 seconds (I actually made 5 exposures at each panel but have not stacked them as yet since one exposure turned out pretty good).
