Astrotracer capable of field derotation

Pentacist · 07-21-2012, 06:58 AM

Hi,

Does anyone know whether the Astrotracer function is capable of eliminating the field of view rotation induced by earth's rotation when the camera is mounted on an altazimuth mount found on many popular Schmidt-Cassegrains ?

Cheers

I would think, the Astrotracer function is meant to be used with a stationary camera. Therefor it needs the GPS info about its location and the orientation of the camera. In that case the two-axis movement on your mount would render it basically useless, as it wouldn't "know" how to account for this movement.

That's what I suspected. Thanks
