Guide Cameras

The ASI120 mini-camera offers you very good performance for guiding.  Very inexpensive and does a good job.

ASI 120MM Mini 

Smaller pixels and good QE makes this an excellent guide camera.  It is not as sensitiave as the 174mm, but is much more ecomonical.  I actually have two lf these in my arsenal.

ASI 290mm Mini 

Updated version of the ASI290.  I now use this as the guide camera in my observatory setup..
