TeleVue 10 Micron Indicator Kit for 2.4" Focuser
This TeleVue 10 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 10 microns 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.
