Astrophotography
summary
Covers concrete methods and results: uses 150-second exposures for deep-sky shots, compares wide‑angle, deep‑sky and planetary (each ~10× different magnification and cost), and shows equipment choices — aperture, tripod versus star tracker, and a barlow lens for magnification. Describes calibration and polar alignment and that polar alignment takes an hour if you’re good, three if you’re bad, mentions stacking high‑FPS video frames for planetary work, a homemade focuser tool, trips to Iceland, and successful lunar and solar eclipse captures.
