Focuser: Digital Indicator for 2" focusers
Digital indicators are precision instruments for computing real-time focuser movement on Tele Vue telescopes. They are essential for returning your system to a pre-determined best-focus position or checking that it hasn't changed. Kits exist for Tele Vue scopes with 2-inch focusers and 2.4-inch "is" scopes. All kits have indicator with LCD display, data port, 0.5" motion range and all mounting parts.
All indicators accept the optional Indicator to Computer RS232 cable connector for displaying readout on computer with free downloadable software. Most exciting, the indicators and other accessories can be employed as a closed-loop autofocus system with Focusmaster Computer Interface.
