TeleVue 1 Micron Fine Indicator Kit for 2.4" Focuser
This TeleVue 1 Micron Indicator Kit for 2.4" Focuser is designed specifically for use with TeleVue's scopes with 2.4" focusers. It will indicate the focus position down to as small as 1 micron of focus travel. NOTE: One micron equals one millionth of a meter.
Digital Indicators are precision instruments for computing real-time focuser movement on Tele Vue scopes. They are great for setting a pre-determined best focus position for imaging purposes or verifying that it has not changed due to temperature drifts or mechanical creep. The Digital Indicator converts the linear movement of a piston to register the exact translation of that piston into a digital display of the displacement (in this case of the focuser) so the user can see exactly if and how much the focuser has moved.
