Where is it? Celestial coordinates explained

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
