USB_Focus is a robotic focusing system for astronomers
motorize your focuser and control it from your computer, or by hand with or without computer
It connects to your computer USB port (or USB Hub 2.0 or 1.1), and does not require any other power supply even for the stepper motor
It connects to an external digital temperature probe, 0.1°C accuracy and can automatically follow best focus for the all night (temperature variations), see documentation for initial configuration
It comes with a handpad for manual electronic focusing and with an ASCOM driver for computer assisted focusing, see documentation for compliant softwares
It pilots a custom motor and reducer providing high accuracy (8000 positions per turn) and high torque (more than 85 oz.inch). It is backlash compensated.
Several adapters are available to adapt to your specific focuser (flexible couplers, motor brackets,..)
USB_Dewpoint is a remote controller for Heaters
once your imaging session is running well, you often feel uncomfortable when humidy starts.
Until now you had the solution to heat your tube or mirrors as much as you could. With major drawbacks like energy waste, creation of turbulence inside of in front of the tube,...
USB_Dewpoint, is a new way to answer humidity issues.
First it calculates in real time the Dewpoint, thanks to ambiant humidity probe close to your instrument. It also connects to 2 external temperature probes (attached to tube or mirrors) and compares these temperatures to the Dewpoint. If temperatures too close to dewpoint it heats in a smooth or aggressive maner. We can also call it a heating regulator.
Second, if no heat required, USB_Dewpoint only uses 0.05W to run.
It connects to computer USB (or HUB 2.0 / 1.1) to operate remotely and can be operated manually or in autonomy.
It handles 3 outputs for heaters or any 12v DC powered equipments (flat box, fans,..) (3x 24W).
