- The backfocus of a camera is the distance from the plane of the sensor to the front of the camera. These measurements are available on all of our astrophotography cameras. To calculate the backfocus of your setup, add up the backfocus of all the separate components. For example, if we take an Atik 460EX camera, this has a backfocus of 13mm.

Similarly, Maksutov-Cassegrains (Maks) also have large back focus distances.

If your camera chip is too close or too far away, then the elements will not actually perform their intended corrections. If your sensor is say at 48mm or at 67mm away, you may still see curvature, or still have coma affecting your images.
