Comments about Baader Planetarium Baader AstroSolar Film (Visual, ND 5):
For greatest success and safety, follow the supplied instructions carefully. I made my filter cell from black poster board, locally available, so no painting was necessary. Shows sunspots well, and would be effective for observing eclipses.
Comments about Baader Planetarium Baader AstroSolar Film (Visual, ND 5):
Like most casual astronomers, I like to observe the sun when there is sun spot activity but I don't want to spend $75+ on a filter that I'm only going to use once in a while. With Baader Solar Film you can make your own Solar filter for $30 or less and get great/safe views of the Sun! You buy the size sheet of film for your scope (so there is little waste) and make a custom cardboard cell for you scope - in 30 minutes you can be observing the Sun!
Comments about Baader Planetarium Baader AstroSolar Film (Visual, ND 5):
I recommend Baader Solar Film because it's durable and displays a pale yellowish white sun. Ordinary Mylar displays a blue sun.
