I am using a Baader Solar Filter that I had to make up the cell from the sheets of solar film. I could only get the film from My Astro Shop as Bintel were out of it. $39 for an A4 sheet.
This is a single frame taken with an 80mm scope, no Barlow, with a Canon 400D. Just to give you an idea on colour. Mind you this was the first time I had used this type of film so results are less than perfect
