L-Mount with Knob for Heavy Duty Planetary Astro Tracker
This is a L-Mount with a 3/8" hole on the Tracker side and a 1/4" hole on the Ballhead side. You can also screw a 12mm counterweight shaft in the L-Mount.
If you loosen the knob a little, you can align and balance your camera comfortably.
if you want to use a counterweight, make a 12mm shaft with a 1/4" thread at one end. This thread then goes through the L-mount into the ball head.
A suitable counterweight is available from Sky-Watcher.
I printed the L-Mount with Princore Carbon PETG, and it is very stiff.
Update:
Much more stiffer is the L-MountHD (HeavyDuty) with the 12mm counterweight shaft.
Happy printing!
