PET-coated Adjustable Solar Filter Film for Astronomical Telescope Sun Observing
Feature:
New generation, double-sided bright silver coating
This solar film is actually a new type solar filter, it is different from a traditional solar filter(Baader film), you can understand it as "PET-coated aluminum foil film"
The main difference from the traditional Baader film is that the sun looks red via this filter, while via traditional Bard film looks like gray sun.
