What's the difference between RA/DEC and Alt/Az? Why use both? In this video I will explain what a coordinate system is, and why we often use both an equatorial coordinate system (RA/DEC) and a horizontal coordinate system (Alt/Az) in amateur astronomy. This is part of a series called Five Minute Fridays where I will be explaining one concept in under five minutes each week. #fiveminutefridays #nebulaphotos • Book recommendation-- Longitude by Dava Sobel: https://amzn.to/3itld5o • ============================= • Supporting this channel: • ============================= • ◦ I'm on Patreon: / nebulaphotos • ◦ One-time donations: https://paypal.me/nebulaphotos • ◦ Shopping for astrophotography gear, you can use my affiliate links: • High Point Scientific: https://tinyurl.com/highpoint-nebula • OPT: https://bit.ly/31XDk9d • Agena Astro: https://tinyurl.com/agena-nebula • Amazon: https://amzn.to/31rYb56 • Modification service at Astrogear.net: https://www.astrogear.net/?ref=nebula... • ◦ You can use my referral code when buying subscriptions to Astrobin: • New accounts- www.astrobin.com/accounts/register/?r=NEBULAPHOTOS • Existing accounts- Use Promo Code: NEBULAPHOTOS • ============================= • Social: • ============================= • Twitter: @nebulaphotos • Instagram: @nebulaphotosdotcom • Astrobin: https://www.astrobin.com/users/2ghouls/ • ============================= • Creative Commons Media: • ============================= • Celestial Sphere by ChristianReady, CC BY-SA 4.0, via Wikimedia Commons • Ra and Dec on celestial sphere by Tfr000 CC BY-SA 3.0 via Wikimedia Commons • Ra and dec demo by Tfr000, CC BY-SA 3.0, via Wikimedia Commons
