This review is from: Baader Astro Solar Film A4 Sheet (Electronics)
I have always wanted to use my telescope to look at the sun and this film provides a low cost way to make your own objective filter to do so. The film was supplied as an A4 sheet and came complete with full and comprehensive instructions on how to incorporate it into a home-made housing. I had anticipated the procedure somewhat and had already fabricated a housing prior to receipt. Mounting the film to the housing was a little fiddly but the tips in the instructions were extremely helpful and I would say that if you followed those you would find it well within your ability to obtain a satisfactory result. You can see the steps I took to manufacture the filter and the first images I obtained through the eyepiece at my Youtube site [...]
Telescope House who supplied the product were prompt with delivery and even furnished me with a 'prize draw number' offering the chance to win astronomically-oriented prizes every week with odds far better than that offered by the Natonal Lottery!
If you wish to see the transit of Venus (when that planet passes between us and the Sun) in June this Year then this is a great way to do it.

Andrew Johnson says:
Is this the ND 5 or 3.8 film? The ND 5 can be used safely with a Telescope the ND 3.8 is only really suited to cameras. I think I will buy from a site which specifies the film density before fitting this to my scope.

According to the sheet, which you probably can't read in the image, BAADER only sell the A4 size filter in ND 5.
The ND 5 and ND 3.5 come in 1/2 sqm packed in a poster tube. The 3.5 also carries a warning as to use. Good Luck, Andy
