Orion_Hörnli
This deepscape image shows the Orion Nebula and the Running Man Nebula setting behind the Hoernli mountain station in Arosa, Switzerland.
Such images tend to raise a lot of skepticism, but this is a real alignment:
Sky and foreground were captured from the same tripod position and during a single night, with the same equipment and at the same focal length. I only shut down the tracking of my mount when Orion Nebula was in the position you see in the image, captured the foreground an recombined sky and foreground in post processing. Check the behind the scenes photo of me capturing this deepscape:
The small field of view due to the long focal length (1000mm full frame equivalent) makes precise planning to find the exact shooting position a must. A small error of a few meters is enough to make the nebula miss the foreground features.
If you want to learn to capture such deepscapes, do not miss my virtual presentation at the 2021 NightScaper Conference. All conference presentations will be available for online viewing for one year.
