1. Last Minute Cheap Solar Filter

    Tonight is the last Venus transit until 2117 and I didn’t really want to spend a ton of money on an off-axis or full aperture solar filter for my 130mm reflector. Looking around a bit I found that a common kind of black polymer sheet is often used to make less expensive filters instead of the more common (and expensive) Baader Planetarium AstroSolar Film.

Yeah That's Me.
