3.5" Focuser Drawtube Dust Cap - Zero-Profile Delrin Cap Fitting the 3.5" Doveloc Adapter (A5071)


The A5071 Dust Cap is a zero-profile part that was originally designed for the Starfire 110GTX to minimize length in its airline-compliant Pelican case. It has a machined Doveloc-style dovetail that fits all 3.5” focusers that use our Doveloc adapter (S35RFAA).

This makes it very useful when removing your imaging system or visual setup and wishing to use a dust cap to protect your open telescope tube. It is a more elegant solution than using an ugly red rubber stopper!

The A5071 Dust Cap is a CNC machined black Delrin part.
