Geoptik Nadirus 2" Filter Holder for Dobsonian telescopes

Geoptik Filter Drawer for Newtonian telescopes and especially Dobsonians

The filter drawer accepts 4x 2" filters. The filters always click into place in the optimal position. The drawer is mounted to the inside of the tube. The drawer is completely made of black anodized aluminium.

The Geoptik filter drawer is optimized for NADIRUS Dobsonian telescopes, but you can also mount the filter holder to other Newtonian telescopes with a low-profile focuser (it must not protrude into the tube, neither its drawtube). Fastening to the tube is made by four screws with the distances 91 mm x 55 mm.
