I bought this Celestron Eclipsmart Universal Solar filter for my 180-600 mms lens through Amazon Canada a while back. Today I received an email from Amazon stating that it might not be safe to use as this product is not in American Astronomical Society’s list of safe suppliers of solar eclipse viewers and filters. The AAS website does list Eclipsmart so I am not sure what's going on here. Did anybody receive any similar warning from Amazon or has past experience using this product?
