Is this article of any help or are you thinking of shooting sunspots, prominences etc?

Not something I've ever tried since I was a lad. Back then I constructed a box to attach at the eyepiece end of a telescope so that I could use a technique called solar projection. I used this to photograph a sequence documenting a partial eclipse of the Sun. The page Solar Observing tips by John Mcconnell FRAS contains some wise words. Pay particular attention to his advice about staring at the Sun through a telescope or telephoto lens without using specialist filters.

As far as filters are concerned, I have successfully used BAADER AstroSolarâ„¢ Safety Film for visual observing and I see no reason why it can't be adapted for photographic use but please read the technical specifications more closely than I have just done to make sure. :idea: The big trick with the Sun is to recognise that while the intensity of the light can dazzle it's actually the unseen infra-red component which can blind you (and damage equipment) and that the retina doesn't contain pain sensors, as far as I am aware. :evil:

Another site which may be of interest is Thousand Oaks Optical. Probably the most "full on" experience would be to use kit like that made by Coronado. Check out this Sky & Telescope article about using the Coronado PST. I haven't tried products from either manufacturer, I'm afraid.

I've just scratched the surface here but as you learn some of the terms you can do some more targeted Google searches.

Bob.
