Notes on astrophotography, equipment, image processing, and lessons learned during nights under the stars.
Almost eighteen centuries before Copernicus, Aristarchus of Samos proposed that Earth moved around the Sun. His idea was remarkably close to reality — but the measurements needed to prove it did not yet exist.
For centuries, Babylonian scholars recorded the positions of the Moon and planets, eclipses, weather, river levels, prices and political events. Clay tablets turned observations of the sky into data that could be compared and used to recognise cycles.
M31 was the second of four targets captured during a field test under darker skies. The goal of the night was not a single perfect image, but to see how the complete setup performed away from home.
Before astronomy asked what stars were, the sky served as a clock, a calendar and a map. The history of measuring the Universe began with a very practical need.
How do you photograph a faint nebula that is almost invisible to the human eye? Using NGC 7000 as an example, this article explains long exposures, guiding, stacking and image processing in simple terms.
This is how the Recon setup moved from short Nikon D3400 exposures to stable 180-second frames after guiding was introduced. The change made it possible to collect more signal in each exposure and build much longer deep-sky sessions.
