+3 on the safe mounting and use of the solar filter , I used to use 2 small strips of duct tape as well as the felt packing and nylon grub screws on my now sold Kendrik solar filter , you cant be to safe especially if friends and family want a look .
Baader solar filter material is very safe to use , millions of people use it world wide .
I also used a " variable polarising " filter screwed into the eyepiece to tone it down a bit .
I now use a Lunt Hershell wedge I got from Bintel and you cant get safer than that , but these only work on refractors and are quite expensive .
