PHOTOGRAPHIC FILTER ONLY!
The cells are aluminum and all have three nylon thumb screws to facilitate a secure fit on the front of your telescope. The filter material itself is BAADER AstroSolar Film. This film has set a new standard for white light filters and gives a very pleasing and high resolution image. The image color is a bluish white. The filters are available in photographic film also and this must be specified in the comments when ordering. Also available are 52mm and 82mm solar filters that can be installed in the Kendrick Kwik Focus lens caps made to date except for those caps that have holes larger than 3" or smaller than 2". These make the Kwik Focus into an excellent off axis solar filter. The filters consist off an insert that is siliconed into one of the holes of the Kwik Focus. Into this the solar filter can then be screwed.
