Most astro shops sell solar film. I brought an A4 size sheet for about $40.00
from Star Optics on the Gold Coast.
Also I dont quite agree with Popeye assumption solar film is better to observe
sun groups/spots. To a degree this might be true as it is cheaper with solar
film than a HA scope aperture for aperture. What Solar film wont show you
is the surface filaments and Plague associated with the sun group. Also
the granulations around the sun group is akin to swirling currents all
observable in a PST. You can watch it change over several hours and some
granulations changes over several minites. It's an awesome thing to
observe, especially sitting there feeling the very heat it's all creating. I
like to get out there with a good sun hat, a towel, and half a dozen beers
in an esky
once you have seen the Sun in HA it's awe inspring and
even a touch scary, but certainly a crowd pleaser.
