-
Remote, microprocessor-controlled pressure tuning for Lunt PT telescopes—USB-controllable from anywhere using compatible software*.
-
Retrofit friendly: add to any Lunt Pressure Tuner (PT) model without returning the telescope; a simple 1/8" airline links the controller to your scope and can be cut to virtually any length.
-
Two-button simplicity: one button increases pressure, one decreases; digital feedback and status indicators keep you on target.
-
Rock-steady bandpass: sealed system can be factory or user-programmed to your center-wavelength setpoint; holds that setpoint at any altitude for a given pressure.
-
Precision control: pressure accuracy to 0.3 PSI, delivering repeatable, fine tuning for on-band H-alpha performance and reliable imaging workflows.
-
Temperature smart: auto-compensates for internal pressure changes caused by significant temperature swings.
-
Closed-loop feedback: correlate pressure changes to Doppler-shifted solar events to study filaments, active regions, and dynamics with confidence.
-
Power anywhere: runs >12 hours on the internal rechargeable battery; accepts 12–15 VDC external power (120/240 VAC→12 V adapter) to run and charge simultaneously.
-
Flexible installs: retrofit via an adapter on the PT knob, or order future PT units with a quick-disconnect at the PT input (removes the knob entirely).
-
Smart startup: automatic vent & ambient-pressure set routine on power-up for consistent baselining, every session.
-
