The Sky Watcher Electronic Shutter Release Cable AP-R3C (C3) is designed for serious astrophotographers and telescope users who require vibration-free remote shutter control for their compatible Canon EOS cameras. It provides a reliable, hard-wired connection that ensures consistent exposures during long-duration imaging sessions, though users should note it requires manual camera settings for timing as it lacks an integrated programmable timer.

No, the C3 connector interface is specifically wired for the Canon EOS series listed.
No, it is a passive device that draws a negligible amount of power from the camera body.
Yes, but you will need to rely on your camera's internal intervalometer settings or external software, as the cable itself does not contain a timer.
The cable is designed for standard field use, but it is not waterproof. Avoid exposure to heavy moisture or rain.
Yes, the R5 is compatible with this cable model.
Ensure the cable is fully seated in the camera remote port and verify that the camera is set to a shooting mode that supports external shutter control.
Check the cable for tension; ensure there is enough slack so the cable does not pull on the camera port as the telescope moves during tracking.
To use the cable, insert the C3 connector into the dedicated remote terminal port on your Canon EOS camera. Ensure the camera is powered on and set to the desired shooting mode before triggering. Compatibility covers various Canon EOS models including: R5, 2000D, 7D, 10D, 20D, 30D, 40D, 50D, 1D MkIV, 1DS MkIII, 5D MkI, and 5D Mk3. For care, avoid sharp bends in the cabling to prevent internal wire fatigue, and store the cable in a cool, dry place when not in use. Clean the connector pins periodically with a dry, lint-free cloth if connectivity issues arise.
