Sirius diffraction spikes and atmospheric turbulence effect
updating note: “For some reason this video has been having many visits and comments from people who are uninformed about science and the cosmos, preferring to intervene here with their faith based fantasies and wishes... To all, just keep in mind this is just the star Sirius, shot with a Canon 550D through a 200mm Newtonian telescope with a bahtinov mask in front of it... Before citing your bible verses or reporting your abduction by the UFO coming from the gate sirius, just breath, calm down and make an effort to learn about the universe where you actually live in (and I don’t mean your own head...)“
Hot air coming from my mouth when talking and breathing towards the light path before light reaches the telescope. Huge effect on imaging, apparently.
This video was made right after a careful collimation. An asymmetrical longer spike is constantly seen, even with the scope in focus, achieved with a bahtinov mask. The presence of this extra spike is not completely understood by me,
