Hedrick Focuser (200340)

I was a little worried about hanging a heavy camera rig off this thing, but the 20lb payload rating held up without a hint of droop or slip during a full night of imaging. The leadscrew drive feels rock solid, and even with a cooled camera and filter wheel attached, focusing stays precise with zero

The 5-bearing focus tube is so smooth I can micro-focus without any image shift, even with a heavy camera rig attached. Handles my full imaging payload without any slippage—a huge upgrade from my previous focuser.

Finally got this installed on my imaging rig last night. The leadscrew drive feels incredibly solid, and it handled my camera and filter wheel combo with zero slippage. No more focus drift during those long narrowband exposures.
