PulsarFab · open astronomy
Your observatory.
Your equipment.
Your control.
Open hardware for the rig. Open drivers for the gear you already own. Build, connect, and understand the equipment behind your next night of imaging.
Regain control of your equipment. Our astronomy drivers connect cameras, rotators, filter wheels, focusers, and flat panels through native NINA, native Windows ASCOM, or an Alpaca server.
Software
Meet PulsarFab regain.
Retryable camera capture. SDK-free device drivers. One Alpaca server for your rig. Choose the use case that fits your setup.
Save the exposure
SDK-free drivers for ASI2600MM Pro/Duo, ASI6200MM Pro, ASI676MC, ASI662MC, and ASI585MM Pro can reread an image after a failed download. SDK mode covers more ASI cameras.
