The Filter Switch allows you to view any deep-sky object unfiltered, or with filters instantly. You never need to move away from the Binotron 27 Eyepieces! This filter switch can be added to our S2 or R1 Power Switch Star Diagonals, or The Binotron 27 itself. Focus is not an issue when the Filter Switch is added to a Binotron 27 used with Newtonians or with The Binotron 27 SCT Super System where it is also added to the Binoviewer. 


The Filter Switch includes two internal 2" filter carriers. These can be quickly slid out of the switch housing. Add extra 2" carriers if you want to use more than two 2" Filters. Add an extra 2" carrier and a 1.25" stepdown carrier for any 1.25" filter that you plan to use. Note: Stacked polarizing filters are too thick to use in this system.


The images show The Filter Switch attached to a Binotron 27 Super System and also an S2 Power Switch Star Diagonal (These are not included with a Filter Switch order).

Note: If the Filter Switch is added to the star diagonal, single eyepieces will likely not reach focus if they normally have less than 1" additional in travel remaining when used with a conventional 2" star diagonal because of the added thickness of the filter switch.
