How to project a COLORIZED turly live image of the sun for under $100 Before I had a nice scope, for interesting "Sun" things, I would just borrow a few pairs of sunglasses from people and stack them. Around 4-6 does a great job. Then you can look directly with your own eyes. Truly amazing, and dirt cheap too. I wonder if you could duplicate this layering technique with something like that stuff they use to tint car windows. |

Quoting: Anonymous Coward 15640397 there is a thicker, "reusable" window tint that you can get at walmart or wherever probably. It's glueless, supposed to stick through static I guess, or suction maybe. I've used it before, and think you could probably do this. Either layer another filter with it or layer a pair of sunglasses with it. Waaaaaay cheaper than $100 |

In fact I wouldn't be surprised if that is the exact same material but you are paying a 1000% markup on it because it is labeled as a "solar filter". |

How to project a COLORIZED turly live image of the sun for under $100 You could just go buy a roll of mylar an make your own for like $20! Lots of solar filters are made from mylar and it works fine. Depending oh how thick it is you might need a few layers of it.

Not screaming in terror like the people in the back seat of the car he was driving. |

How to project a COLORIZED turly live image of the sun for under $100 With a small scope, you can not only project the image, but magnify and focus it. In theory, you could project a colorized and focused live image onto something as big as a movie screen during a solar event if you put some time and effort into getting it to focus(I might do some sort of tinkering like that during the eclipse on the 20th). |
