Some how-to pictures online show a very small bright dot near the mirror assembly at the back of the Solarscope, so that must be close to the focal length of the objective, but what then is in that mirror assembly that forms the image on the inside of the screen? (I have a terrible intuition for optics, so if the answer is trivial, I apologize in advance. So it is doing eyepiece projection, which I think I understand (or at least I did during the eclipse when we used binoculars to project an image on a paper plate).īut in the Solarscope, I don't see where the eyepiece function is performed.
ASSF (AstroSolar Spotting Scope Filter) Baader Solar Filter for Spotting Scopes. Dick, 62, and Angel, 44 - who shot to fame in 2016 on the Channel. In the the Sunspotter document they say that it is just a folded refractor and they show an eyepiece suspended under the mirror at the top of the triangle. After 15 years of offering AstroSolar film sheets as DIY-product. ESCAPE to the Chateau fans were left seriously confused when they spotted a big change to the Strawbridges home in a recent snap. The thing that I don't understand is how the image is formed and magnified. Just like buttermilk, milk is high in lactic acid that may help lighten sunspots. It looks like an objective lens in the tube in front and then a mirror held low in the the back and a resulting image on the screen behind where the objective tube is mounted. The lactic acid in buttermilk may help lighten sunspots when applied to the skin. But I've been trying to understand the optics on that one. The DIY Sun Science app (for iPhones and iPads) allows families and educators to investigate and learn about the Sun at home, at school, or anywhere they go.
Jim, thanks for the pointer to the Solarscope.
