belt driven systemThe Avalon Instruments exclusive Fast Reverse belt drive system gives incredible performance in astronomical imaging.

No meridian flip needed

No Meridian Flip NeededOur M-zero and M-uno single arm astronomical mount allows to track an object all night long without the needing to flip the telescope when the mount is passing through the meridian!

Original design made in Italy

mzeroAll our products are developed to be easy and friendly, without maintenance and high quality manufacturing, for giving you the maximum performances for a long time.

PHD2 guide parameters

The best guiding performance with our belt driven mounts comes by using the lowest possible guiding speed ( 0,2 / 0,4 ) , the shortest possible guide exposure ( 1 sec is ok ) and the lowest possible RA/DEC pulse guide duration ( 300 / 600 ) .

Due to the Fast Reverse Belt Drive System fast pulse guide responding, it is strongly suggested to use a smoothed guide settings, to avoid overcorrections/oscillations.

The above PHD2 guide parameters table can be used as starting values that must be adjusted on depending of the setup and the live performance, we also suggest to use the Off Axis Guider, specially with long focal length longer then 800 mm or/and mirror telescopes, to avoid differential mechanical flexure that can create issues on the final star shape quality.
