Telescopes and Eclipses - Safe Solar Viewing

How can you safely watch a solar eclipse with a telescope? We cover that in this video. Probably the most important thing is knowing how to inspect your solar filter to see if it is safe to use. It is the kind of thing that everyone talks about as if you would automatically know what to look for. My old solar filter finally went bad, so I can show you exactly what it looks like when a solar filter is no longer safe to use. I'll also talk briefly about solar wedges (a.k.a. Herschel wedges) for solar viewing. The theme throughout the video is safe solar viewing and what equipment is appropriate for each type and stage of solar eclipse.
