Autoguiding Cameras

An autoguiding camera watches a star and sends tiny corrections to the mount many times a minute, so long exposures stay sharp even when the mount's gears are not perfect. It is the step that takes imaging from 30-second subs to five or ten minutes per frame.

We carry guide cameras from ZWO (including the slim ASI Mini series), QHYCCD QHY5III, Player One Ceres, Sedna and Mars, SVBONY and iOptron. Most are compact 1.25-inch bodies that fit a guide scope or an off-axis guider.

Choosing a Guide Camera

  • Mono sensor: Mono cameras are more sensitive, which means more guide stars, especially through an off-axis guider.
  • Sensor size: A larger sensor finds stars more easily in an OAG's small pick-off field. The IMX174 and IMX585 are popular for this.
  • Pixel size and focal length: With a 30 to 60 mm guide scope, any modern guide camera works well. With an OAG at long focal length, larger pixels or binning help.
  • ST4 port: Some cameras offer an ST4 output. Most setups now guide over USB through the mount driver.

Guide Scope or Off-Axis Guider?

A small guide scope is simplest and works well up to about 600 to 800 mm of imaging focal length. Above that, or with SCTs and their moving mirrors, an off-axis guider avoids differential flexure.

Guide Cameras: Frequently Asked Questions

Can a guide camera also image planets?

Yes. Many guide cameras use the same sensors as planetary cameras and work well on the Moon and planets.

What software do I use?

PHD2 is free and works with almost every camera and mount. ASIAIR and NINA include guiding too.

Why is my guiding poor?

Common causes are poor balance, cable drag, flexure between guide scope and main scope, or wrong guide settings. Send us your log and we will help read it.

Adding autoguiding?

Tell us your telescope's focal length and how you will mount the guider. We will recommend a camera and setup.
