DIY Astronomy (2025)
DIY Astronomy on a Budget — learn how to start stargazing and astrophotography without breaking the bank. In this talk, Prof. Rino (amateur astronomer since 2020) shares his no-nonsense journey: buying second-hand scopes, rebuilding classics, and avoiding the expensive rabbit hole. You’ll see exactly what works for visual observing vs. imaging in the Southern Hemisphere (NZ), plus the free tools he uses every night.
What you’ll learn
• Best first telescope: 8" Dobsonian vs. Newtonian vs. Schmidt-Cassegrain (aperture isn’t everything)
• Mounts explained: Alt-Az vs. Equatorial, field rotation, and DIY wedges for tracking
• Visual vs. astrophotography: planets (lucky imaging) vs. deep-sky (long exposures)
• Realistic “budget kits”: second-hand finds, entry ZWO cams, DSLR mods, phone night-mode
• Simple DIY fixes: moving the primary for DSLR focus, cleaning optics safely, silver vs. aluminum coatings
• Free software that changes the game: Stellarium (incl. VR), FOV calculator, Astrometry.net plate solving, AstroHopper
• Iconic targets & scale: Orion & Carina Nebulae, Andromeda, Milky Way core, Jupiter–Saturn conjunction
• Light pollution basics and how you can help protect dark skies
