What we liked
- + ND 5 density is the standard safe level for direct white light solar viewing
- + 3 inch square piece suits small telescopes, finders and binocular objectives
- + SolarLite film gives a natural looking Sun image
Trade-offs
- - Small piece only covers small apertures, so larger scopes need bigger sheets
- - Needs a secure homemade cell over the front of the scope before any Sun viewing
