Shallow Knob for Starizona RASA 8 Filter Drawer

This is a Knob for Starizona RASA 8 Filter Drawer that will not protrude inside the optical path of your RASA 8. This is curved on both sides to match the curvature of the drawer/camera and the large 93mm camera adapter fastening ring. The incurved "wings" offers good grip with two fingers. *The screw hole position is offset, so pay attention to put it on the side that allow clearance towards the OTA. AS I use a small diameter camera, I've increased the height of the knob for a better grip. If you use a large camera (90mm), you'll need to cut the height a bit.
