This is just a great filter for imaging The Sun in white light
The film gives more detail at the surface around the spots than my old trusted Thousand Oaks
It's very thin and gives exposures at 1/3000 f/11 ISO 160
I highly recommend this if you want a cheap leap into photographing The Sun in white light

All the best from Norway
