Guide cameras

Guide cameras for autoguiding. A guide camera watches a star through a guide scope or an off-axis guider. Software such as PHD2 then tells the mount how to correct its tracking. That keeps stars round through long deep-sky exposures.

What makes a good guide camera

Sensitivity matters most: the camera has to find a guide star in a second or two, even in a sparse part of the sky. Small and light helps too, so it doesn’t weigh down a guide scope or shift during the night. Most mounts take guiding commands over USB through your imaging software. An ST4 port gives a direct cable to mounts that need it.

Guide scope or off-axis guider

A small guide scope is the simplest set-up and suits short to medium focal lengths. An off-axis guider picks off a star from inside your main telescope, which avoids the two drifting apart. It’s the better choice at long focal lengths. Many planetary cameras make good guide cameras too.
