Milky Way at the Old Barn

The galactic centre area of the Milky Way in Sagittarius behind the grand old barn near home in southern Alberta, on June 30, 2019. Illumination of the barn is from twilight to the north, but also from light pollution skyglow from the west off frame at right. The sky is blue from the perpetual summer twilight at this time of year.

Jupiter is at centre. The nebulas and starclouds of the Milky Way show up well here. The southerly Messier clusters, M6 and M7, in Scorpius just skim the horizon at left. The very red star in the “eye” of the Dark Horse is TW Ophiuchi. This is from my latitude of 51° N.

This is a blend of tracked (for the sky) and untracked (for the ground) exposures, with a stack of 3 for the ground and 5 for the sky, stacked to smooth noise. All at ISO 1250 and one minute each, but with the sky exposures at f/2 and ground exposures at f/2.5, with the Sigma 24mm Art lens and stock (not modified) Nikon D750. The sky exposures were through a NiSI Natural Night light pollution filter. The sky exposures are at f/2 to make up for the light loss from shooting thru the filter while keeping exposures short for ease of blending later. The tracker was the Sky-Watcher Star Adventurer.

I added a mild Orton effect glow layer to the image using Luminar Flex.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
