Sunsniper
The filter is home made with AstroSolar Safety Film OD 5.0, 20 x 29 cm
The holder was made with a 3D-printer and fits over the hood of the lens.
For photography there is a less dense filter of 3.8. This 5.0 is for visual BUT only in combination with optics. Do not use it like a pair of glasses!!
Do not touch it with unprotected vingers as the fatty acids in the skin of your fingers will damage the filter!
