What is the main purpose of the Sky-Watcher Canon 5D Shutter Release Cable?
Its primary purpose is to connect your Canon 5D-series DSLR to a Sky-Watcher GoTo mount. This allows the mount's SynScan hand controller to automatically trigger the camera's shutter, which is essential for taking a series of long exposures without causing vibration.
Which Sky-Watcher mounts are compatible with this shutter release cable?
This cable is designed to work with virtually all Sky-Watcher computerized mounts that feature a SNAP port and use a SynScan hand controller. This includes popular models from the EQM, EQ, and AZ-EQ series, such as the EQ6-R Pro and HEQ5.
Will this cable work for imaging the Orion Nebula (M42) with my Canon 5D?
Yes, it's perfect for that scenario. You can program your SynScan controller to take a sequence of multiple, long-exposure images of the Orion Nebula (M42). The cable allows the mount to control the camera, ensuring each shot is taken without any vibration, which is critical for capturing the faint nebulosity and sharp stars in the Trapezium cluster.
Is this cable compatible with the Canon 5D Mark II, Mark III, and Mark IV?
This cable is designed for the Canon "N3" type remote terminal, which is used on the original 5D and subsequent models like the 5D Mark II, Mark III, Mark IV, 5DS, 6D, 7D, and many others in the prosumer line. Always confirm your specific camera model uses the N3-type remote port before purchasing.
Can I use this cable to connect my Canon 5D directly to a computer?
No. This is a shutter release cable designed to connect the camera to the Sky-Watcher mount's SNAP port for control via the hand controller. It does not transfer data. To control your camera from a computer, you will need a separate USB cable.
How do I set up an imaging sequence on my 8" SCT using this cable?
Once your telescope is polar aligned and focused on a target like the Hercules Cluster (M13), follow these steps:
- Plug the cable into your Canon 5D's remote port and the other end into the SNAP port on your mount.
- On the SynScan hand controller, navigate to the "Camera Control" menu under the Utility Function menu.
- Enter the desired exposure length (e.g., 120 seconds) and the number of frames you want to capture.
- Initiate the sequence. The mount will now trigger your camera for each shot automatically.
