Here for your approval, we have the largest filter slide in the world; The Excalibur !

It holds EIGHT 2" filters and has a full length dew/frost heater.

We are installing it on a Redwood red C30 f/3.3 next week. We have the scope apart to add some additional wiring, but there will be lots of pictures soon to come.

Here is the installed filter slide in a C30.

Steve sent us a Astrozap to run his dew system, so we installed it on the UTA.

Here is the filter slide from the inside of the UTA.

Note the dew heater cable that keeps each filter clear of dew and frost.

The Excalibur is manufactured by Roger Greenwood of Astrocrumb fame.

Check out his website @: www.astrocrumb.com

The installation very easy as it just threads on to the rear of the Feathertouch focuser. You guys certainly will not need to pay us to install it on your own scopes, that's for sure.
