How to measure your telescope

Determining the Correct Orion Solar Filter for your Telescope
A full-aperture solar filter is designed to fit over the front of a telescope. It allows safe viewing of the Sun by reducing the light by 99.99% and preventing concentrated heat from entering the telescope, which could cause injury to the user or damage to equipment.

If your telescope is not listed on our solar filter chart, you can determine the size of filter needed for your telescope by taking the following steps:

Measure the maximum outside diameter (OD) of the front end of your telescope.

The solar filter sizes listed on our website refer to the inner diameter (ID) of the filter's foam-lined metal cell for Orion Safety Film Solar Filters, which slip over the front of the telescope. Choose a filter whose size matches the OD of your telescope's front end, or that is up to 0.25 inches larger than the front end.

Installing the Orion Solar Filter on Your Telescope
If your solar filter includes three thumbscrews, back them out to just inside the wall of the metal cell. Alternatively, if your filter includes foam shims, you can install them now to ensure a snug fit. Then place the solar filter over the outside of the telescope. It may require some light force to push the filter into place, but make sure it is seated completely over the telescope. Then lightly tighten the thumbscrews (if included) to further secure the filter on the telescope.

The Orion Safety Film Solar Filter is made with high-quality Safety Solar Film, designed specifically for safe observation of the Sun through a telescope.

Using this streak-free and blister-free film filter is an affordable and safe way to observe sunspots, solar eclipses and planetary transits of our Sun. The durable film polymer shows the Sun in its natural color. This Orion Safety Film Solar Filter has a cell made of aluminum — not plastic like some lower-quality filters — with three safety thumbscrews that grip the front of the telescope to ensure a tight, secure fit. This filter is designed to be used with equipment up to 0.25" smaller than the rated filter size.

Don't miss out on the fun of observing solar activity. Get an affordable Orion Safety Film Solar Filter for your telescope or binoculars! (NOTE: binoculars require two filters.)

This Orion white-light solar filter is designed to see sunspots and granulation around the sun spots on the solar disk. It is not a Hydrogen-alpha filter which shows prominence and solar flare detail. For that type of solar viewing, consider upgrading to a Coronado Solar Telescope.

This solar filter is designed and manufactured in the USA.

Orion assures that all solar filters are tested at specialized labs that are accredited to verify compliance with the ISO 12312-2 safety specifications for solar viewing.

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.
