Celestron Eclipsmart Solar Filter - 8" SCT / Edge HD

This White Light Solar Filter was designed to efficiently and easily turn any 8-inch Celestron SCT or Edge HD Telescope into high-quality solar observation or imaging models, providing a safe and efficient way for your pre-existing nighttime telescope to become a top-notch solar instrument!

With six high-quality Nylon safety screws meant to enable a safe, snug fit for the filter against the telescope's front cap, this filter is secure and firm when in use, doubly ensuring safety by making sure that the filter will stay attached when in use. Every single EclipSmart product from Celestron has been guaranteed by Celestron to strictly adhere to ISO certification standards, which means that they are guaranteed to fall within the legal safety parameters for an object designed to view the Sun.  

The Solar Safe Film was produced in the USA by American Paper Optics, one of the suppliers recommended by NASA for safe solar viewing.  This film fully meets ISO 12312-2, Safe Viewing of the Sun, when used in accordance with solar-safe instructions.

Just attach the EclipSmart Solar Filter to your 6-inch Celestron SCT or Edge HD Telescope, and you'll have a safe, fun, and efficient way of viewing the sun, without any need to buy a new telescope or abandon your 8-inch Celestron SCT or Edge HD. Open up new dimensions of astronomy with just a simple filter on the front of your scope!

Note: Even with the safety and well designed, sturdy nature of this filter in mind, please take care when using any kind of object to view the Sun, and be sure to check for any level of damage to the filter before viewing to avoid any possible risk of damage. The filter is highly durable and well protected by the design, but due caution should always be taken with any solar astronomy device.

Worked great for Mercury's transit of the Sun

I received this product very quickly, just in time to view Mercury's transit. It worked as advertised, allowing me to view the Sun without fear of damaging my equipment or my eyesight. I look forward to the next opportunity to perform some more solar observations with it.

Great solar filter

I used this to watch the Mercury transit. It fit my CPC scope well and showed a clear image of the Sun.

Great value

I bought this for the Mercury transit next week. Works great, attaches to the OTA exactly like the cover does. It comes with velcro too, just to make sure, but that isn't necessary.
