Another Homemade Solar Filter
Back a year or so ago, I built a wood frame solar filter for one of my larger telescopes and, if interested, you can read about it here. This is another blog entry about a new homemade solar filter that I made about a month ago to be used, mostly, for testing purposes but it never hurts to have multiple ways to view the sky, daytime or nighttime. I decided to build this solar filter for two reasons.... 1) I already had the supplies so it wouldn't cost me anything, and, 2) I want to compare one of my Spectrum glass solar filters to this new solar film filter I made as well as compare it to my solar wedge as a comparison between the three types of solar filters. To make this comparison as accurate as possible and to keep as many scientific controls as possible in this little test, I decided that I should use the same telescope and the same camera so the only significant variable in this test would be the filter itself. My small Skywatcher ED 72mm refractor was the best option
