Notes on astrophotography, equipment, image processing, and lessons learned during nights under the stars.
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.
