solar photography filter material in Victoria, British Columbia for sale

50 cents per square inch buys you an opportunity to safely enjoy viewing the sun. This material is the single best white light telescope filtration for solar viewing and has been engineered and certified and used for decades by professional astronomers for this purpose. It is called Baader astrosolar safety film optical density 5. It is designed for use over a telescope's primary objective. I can provide description of how to use, but it is the buyer's responsability to ensure their safety by following all precautions associated with proper use.
Better prices at larger apertures (8x8 and larger and larger apertures allows for greater magnification). While it has been commonly used for such in the past, this material is not intended for solar sunglasses; it is intended to cover telescope, binocular and photographic lenses.
On a lighter note, this unique material allows for observation and photographic capture of high energy events, such as critical nuclear cores, thermonuclear detonations, meteoric fireballs, asteroids hitting the earth, thermonuclear bombs hitting asteroids and asteroids hitting nuclear bombs, and you just know that if any such event happened, no one would be able to really photograph it, and that's a total pity, since all these events seem a wee bit more likely these days. Also we are approaching solar maxima and this material can enable you to see sun spots with astonishing clarity. In fact interfometric tests showed this material is comparable to optical flats, which are absurdly expensive.
I purchased this material bulk for a project and have surplus available at cost. It is brand new, never touched and I include manufacturers instructions... looking at the sun is extremely dangerous for your eyes especially through a telescope which would instantly sterilize your retina (permanent blindness). As such, instructions must be followed with care. Contact me only if you agree to assume all responsibility for its proper use as described by the manufacturer. I can supply the material and some instructions and guarantee what the material is; everything else is up to you.
