Focus lever

A long solid lever on the focuser, so focusing is a light touch downward instead of a twist of the knob.

Action: light downward touch
Replaces: twisting the focus knob

Homemade. The problem it solves is not focus precision, it's what your hand does to the telescope while focusing. Twisting a knob on a 76 mm tube sitting on a light mount applies torque to the whole assembly — the image swims, you wait for it to settle, and by then you have lost the thing you were judging.

A long lever converts that into a small vertical touch. Less torque, and the leverage means a given movement of your hand is a smaller movement at the drawtube.

To find out tonight: whether the settle time after a focus change is actually shorter, and whether the lever has enough resolution at the fine end or overshoots.

Used on these nights

First planet — Venus, low in the west, and nothing to see on it

New swivel, a focus lever, and a darker patch of yard

Three changes at once before tonight: the mount is rebuilt onto a friction-loaded roller-bearing swivel, the focuser has a long lever instead of a knob, and I'm setting up out the back away from the…
