Ian, you'll need to expand. I'm guessing that you don't want to blot it out entirely , so what is it you want to see - the disc? sunspots? surface granulation? prominences?

The best type of filter IMO is definitely a HA filter.... re PST or similar.

Assuming you have a telescope: a JMB/ 1000 Oaks or Baader solar filter to fit the objective will give good visual views of the Sun's surface; If you want to see detail in Hydrogen alpha wavelengths you need a special ( and costly!) Ha filter system.
The cheapest introduction to Ha is the 40mm Coronado PST telescope.

G’Day All,
Thanks for the info about sun filters people I know I was pretty vague about what I wanted. I have Meade LXR75 8”and all I know about these filters is that they come in glass or film. What filter would you use to see sun flares or sun spots and what price would you pay and how are they attach to the telescope and what colour do you see the sun .I have seen photo with the sun coloured red, green or white .I do know that HA filters you need a small bank loan to buy one so I will not be looking at them so out of the rest that are on the market what would be the best to buy and what would you see.

Visual light solar filters

I like the Baader solar film; it gives a clean white image.
The 1000 Oaks and JMB glass filters have a salmon pink image.
All of these filters come in an aluminium cell which just fits over the end of the scope; held in place with three small nylon thumb screws.
