The constellation of Scorpius on 30. June 2018
60 x 1 s, 45 mm, f/2.8, ISO 6400
Stacked with Sequator and processed in Affinity Photo.
A big issue with this photograph was the net, which is installed on our balcony to keep the birds from soiling it. With binoculars, it poses no problem, but with a 45 mm lens with a considerably larger view, the net was clearly visible although out of focus. Stacking averaged out the horizontal bands, but the vertical bands remained.
I managed to salvage the image by performing frequency separation so that most of the detail went to the high-frequency layer. Then I reduced the luminance of the low-frequency layer until the bands were no longer visible.
I intended to photograph the constellation, and I did not expect to see any deep sky objects, but closer inspection showed that several globular clusters are actually visible in the image. They appear just as few pixels wide blotches but are a nice addition to the photo.
