Orion 7745 3.68-Inch ID Full Aperture Solar Filter

Description

Product description Who said you have to be in the dark to do astronomy!
Turning your telescope to the Sun is fun and educational. Watch the march of
giant sunspots, the clouds of glowing vapor in the photosphere, and solar
granulation detail. But be sure to protect your precious vision with a safe
Orion solar filter! Looking at the Sun without one, even for an instant, can
permanently damage your eyes. These full-aperture optical glass filters
deliver superb views of the Sun, without risk to your eyes. While more
expensive than black polymer film filters, Orion solar filters provide better
contrast, a more natural yellow-orange color rather than blue, and are more
durable. They're ideal for photographing the Sun too. The glass elements are
machine-polished and triple-coated with an advanced nickel-chromium stainless
steel alloy for a scratch-resistant surface. The filter passes only a fraction
of the incoming light, rejecting harmful ultraviolet and infrared radiation.
Each filter is mounted in an aluminum cell that slide-fits over the front of
your telescope. Size shown in the chart below is the ideal diameter of front
of telescope; filter will fit diameters up to 1/4" smaller with foam tape
liner supplied. CAUTION: Never look at the Sun, either directly or through a
telescope, without a professionally made protective solar filter installed
that completely covers the front of the instrument, or permanent eye damage
could result. From the Manufacturer A must-have for safely observing the sun
and sunspots without damaging your eyes. Optical white light glass filter fits
snugly over your telescope's aperture to block 99.99% of incoming sunlight.
Glass elements are machine-polished and triple-coated with nickel-chromium
stainless steel. Each Orion telescope solar filter includes three equidistant
thumbscrews, 4x 1/16" thick adhesive foam tabs, and 4x 1/8" thick adhesive
foam tabs for customized friction fit to your telescope. Note: All Orion solar
filters are designed for use with an adequate friction fit attachment.
Thumbscrews should ONLY be used to keep filter securely in place once a
friction fit has been achieved
