AlpacaBridge

Every driver, ConformU-verified.

AlpacaBridge ships native ASCOM Alpaca drivers for real astronomy gear. Each one is validated against the official ASCOM conformance suite on the exact hardware it supports. If it's listed here, it's been proven on Debian 13 (Trixie) arm64.

verified

Proven, not promised

Only drivers that pass ConformU verification are listed. Each entry links to its validation output in the AlpacaBridge repo. No "should work," only "does work."

developer_board

Vendor-backed

Manufacturers including iOptron, Player One, QHY, ToupTek Astro, and Wanderer Astro supply hardware directly for driver development.

autorenew

Always growing

New drivers are added continuously as they clear conformance. This page is generated from the full matrix and tracks it automatically.

Don't see your exact model?

The devices listed below are the ones we've individually ConformU-verified. Because each driver is built on the vendor's own SDK, other models from the same brand generally work too. A listed camera, mount, or focuser means its whole family is very likely supported; it just hasn't been verified on that specific unit yet. If you run gear that isn't listed, let us know on Discord and we'll help confirm it.

Platform

All drivers are built and validated on Debian 13 (Trixie) arm64 (Raspberry Pi 3B+/4/5, Rockchip SBCs, OrangePi, iOptron iMate). Kernel 6.12.75-v8-16+ or higher is required for full ZWO EAF/EFW compatibility. See the install guides to get set up.

Cameras

34 cameras across eight brands, from dedicated cooled astronomy cameras to everyday DSLR and mirrorless bodies.

Astronomy Cameras

28 cameras from six brands, cooled and uncooled, with cooling, dew-heater, and pulse-guiding support gated per model.

DSLR & Mirrorless

Supported through the GPhoto driver, which talks generic PTP rather than a per-model SDK, so other Canon, Nikon, and Sony bodies that libgphoto2 recognizes should work too. ISO is exposed as a discrete gain list, and bulb exposures past the body's 30 s ceiling are supported.

Mounts

Alt-az and equatorial mounts over USB/serial or Wi-Fi, including full ZWO harmonic-drive and iOptron support, plus a direct motor-controller driver for Sky-Watcher Wave and EQM-35 Pro.
