Grasplatz

When diamonds were first discovered in Namibia, the German colonists of the early 1900s built a lot of infrastructure to assist in its mining. This included a railway line from the coastal town of Luderitz to the interior of Namibia towards Aus. Prisoners from the nearby Shark Island were used to build the railway line and it is said that for every hundred meters of the railway line built one prisoner lost his life. Grasplatz was one of the stations built around the route, in typical German branch line style and lies in an abandoned unused state today. As with many other abandoned structures littering the Namibian landscape, it forms a great foreground element against which to frame the beautiful Bortle 0.5 skies of Namibia.

I used my full spectrum modified Nikon D850 with a UVIR blocking filter to first capture the station with a long exposure of 8 minutes and further invoked long exposure noise reduction in camera to mitigate hot pixels. Numerous other shots were taken to light up the interior and exterior of the station building with a light panel. I then moved the tripod to get a clear view of the sky to the horizon and shot a tracked 4 minute exposure of the sky with an IDAS HeUIB filter. A further 30 secs exposure was taken with a fog filter to create halos around the stars. These multiple exposures were then blended together in Photoshop. For the purist the ground exposure was at 225° azimuth while the milkyway was shot at an azimuth of 247°. I do take these liberties from time to time in the interest of a better composition, a habit I must break!!

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.
