$Inside Grande Pines Observatory: Top-of-the-line amateur astronomy A look inside Grande Pines Observatory! This observatory has featured in multiple timelapses, appearing in my channel trailer, the Barn Door tracker video, and the Polaris Timelapse video, but Ive never actually done a video about the observatory and all of the awesome equipment inside, so here it is! Grande Pines Observatory is operated by my dad (the astronomer). He is also the presenter in this video. I got to have fun shooting somebody elses project this time! Hope you enjoy! The gallery of images at the end of the video were taken in this observatory, some with the old 10 f/4.0 Newtonian telescope that the telescope featured here replaced.

Star-Stabilized 360 Camera #perfectloop #astronomy

$A laser pointer at 2 billion fps makes the speed of light look... kinda weird Ive upgraded! It took almost a year, but today I finally get to show off a TWO billion frame per second camera! I really want to record refraction, interference, and other awesome stuff with this camera, but today Im looking into a really strange quirk of the speed of light. In a way, understanding this weird phenomenon is kind of a prerequisite for everything else I want to do with this camera - I hope you find it as interesting as I have! MANY more technical details for the curious: https://www.youtube.com/playlist?list=PLAYHMTkuzdT3Zwk3UialNtxXrpkmaC_ZI bonus points to hakonjdjohnsen for advice on colormaps, R520 for a typo, and @dl33 for the top suggestion in last videos comments!
