SoundStepper is a telescope controller to help you with your work, uses audio hardware to real-time control step motors of a telescope mount, it requires only simple external analog current amplifier to operate.

Features:
1. SoundStepper can control up to 3 motors (RA, Dec and focuser) of a equatorial-mounted telescope.
2. SoundStepper can control any type of equatorial-mounted telescopes with step motors. Manual-pointing mounts (ex: barndoor, poncet platforms, "polar axis", threaded-rod driven mounts), "meridian-flip" mounts (ex: GEM or cross-axis), and "no-meridian-flip" mounts (ex: Fork, yoke, horseshoe, split-ring).
3. SoundStepper can "sync" and "go-to" manual-pointing mounts, making faint objects easier to find (manually center scope on a star, find the star in Cartes du Ciel, right-button, "sync", right-button on faint object, "go-to").
4. Using analog control, SoundStepper drive step motors with quietness, smoothness and linearity. With adjustable linearity, the typical wobbling is 1/20 of step. Like microstep controllers, it can put the motors in any position between step positions.
5. No PICs, no small SMD microsoldering, no EPROM, no switching interference. SoundStepper uses a simple (SUGGESTED) analog current controller, plugged on cheap USB-AUDIO device, to drive a stepper.
6. No MS-DOS dedicated computers. SoundStepper does realtime control sharing the computer with planetarium, photo/video capture and others applications, in Windows. It take advantage of the audio devices buffering and autonomous playing.
7. SoundStepper has built-in PEC and NPEC (periodic and non-periodic error correction systems). With NPEC, the entire threaded rod can be "trained", enabling the use of cheap thread rods, and the "thread rod/nut/arm" system (like "Astrotrac").
8. Main screen with keyboard arrows "control box" (find, center and guiding), go-to, flip, park/unpark and focuser controls.
9. LX200 command interface compatibility, enabling the use of LX200 ASCOM driver, through any virtual serial-TCP redirector. The TCP/IP interface enable control the scope from a remote computer.
10. Configuration screen with many controls, to match SoundStepper with your motors and mount.
11. Autosave and autorecover last telescope and motor positions (crash recover)
