Make your own solar filter with this handy solar sheet
This thin film provides orange/yellow views of the Sun for observing sunspots. It comes in a 12" x 12" or 9" x 12" sheet (please select size in dropdown menu above), so you can make your own cell and put the film in between. The film blocks out 99.999% of sunlight for safe observing.
You can also make solar and eclipse viewers with this film. See Ian Littlewood below in a short video showing you how to do this. Safe and fun to do.
The film is a black polymer thin film and is 0.002" thick. This film is a lot stronger and a lot cheaper than its competition making it the film to go for!
Next day shipping on this item!
I used this film with a Celestron powerseaker, and a 30mm eyepiece.the view of the sun was fantastic. I had to construct my own filter for the viewing, and this was perfect for the job. It cut easy, and glued into position well. It also makes lovely solar glasses. It appears to be quite durable too, so is good should you drop your home made filter. I find it best on a 70mm telescope for viewing the sun.

I've used this for a while now and find it good for imaging the Sun using my 8" SCT. Works great with a ASI120MM and an Astronomik IR Pro (742nm) Ir filter.However that is the problem if used visually the filter may block visual light but lets through a lot more Ir.So if you want a visual filter you will need an Ir blocking filter as well.
