  1. Hi all! Long time since I've posted on the forums. Looks like an upgraded system. Nice I just wanted to share something that I think is extremely awesome! I didn't know exactly where to post this... I thought maybe in science, but it's also photography... I dunno. First of all... What is Schlieren Photography? From Wikipedia: "Schlieren photography is a visual process that is used to photograph the flow of fluids of varying density"... In this case -- Air. I watched this great tutorial on YouTube on how to make a homemade Schlieren setup, and it's pretty simple. Unlike the tutorial, which uses a razor blade and a circuit-board for the LED, I just used a bit of aluminium foil and a phone's LED. This is what it looks like professionally: This is what it looks like with my setup - It's me lighting a lighter. My full video (better quality) can be seen here: https://www.youtube.com/watch?v=6BulKfpf35A The dark circle in middle is, of course, the secondary mirror's holder. I placed my hand near the opening of the main tube. Quick setup explanation and simplifications: I placed my extended telescope at one end of the room, and the camera setup at the the opposite end of the room (it's not a big room). I used aluminium foil instead of a razor blade. I used the phone's LED (uncovered) instead of a circuit-board LED. Otherwise, I just followed the linked tutorial. Here is a crappy schematic of the setup: Here is the camera setup: So when the sky is cloudy, here's something you can try out I think it's absolutely amazing. Not "first-time-seeing-Saturn" amazing, but pretty spectacular and interesting! Have fun! - itai -
