Whilst Surbiton is hardly a dystopian concrete jungle, it does have a darkness score of 18.1 mag/arcsec² as I measured it, so patience is very much required to see the astonishing beauty of the night sky. I should have a bumper sticker saying “urban astronomers do it all night every night, and then do it in software.”
Pi 4 + Camera Module 3 (IMX708). Nightly star-trail and pole-derotated stacks with hot/cold pixel masking.
Celestron 76/300 tabletop Newtonian at prime focus — pointed at the pole, no tracking, frames de-rotated and stacked afterwards.
Pi with a Camera Module 3 Wide (IMX708 Wide), day and night astro along the ecliptic. A v1 camera (OV5647) is fitted but not used.
The logbook — what an instrument showed on a given night and what we concluded from it, tagged by instrument and linked to the pages of the instruments themselves.
Curated one-off captures — meteors and fireballs, lightning, aircraft, satellites, odd frames caught mid-inspection, and daylight test shots.
Canon EOS 2000D DSLR — 30 s ISO-1600 fixed-focus subs, fixed mount. Nightly short-trail star-field stacks with hot/cold pixel masking.
Zenith-pointing OV5647 — nightly stacks, plate-solved frames, derotation experiments.
