Parameters for PHD2 with Avalon mounts
The best guiding performance with the belt driven Avalon mounts is achieved when using the lowest possible guiding speed ( 0.2 / 0.4 ), the shortest possible guiding exposure ( 1 second is ok ) and the lowest possible RA/DEC pulse guiding duration (300 / 600).

Since the Fast Reverse Belt Drive system responds quickly to pulse guidance, it is strongly recommended to use a smoothed guidance setting to avoid overcorrection/oscillation. The PHD2 guide parameter table below can be used as a starting value to be adjusted depending on setup and live performance. We also recommend the use of the off-axis guider, especially for long focal lengths above 800 mm or/and reflector telescopes, to avoid differential mechanical bending which can cause problems with the quality of the final star shape.

The parameters given below refer to the guidescope. 

It is important to note that the focal length of the guidescope should be at least half of the focal length of the main telescope to achieve good guidescope performance.

The pixel resolution of the guiding camera should not be too low compared to the main camera.
