Have a Question? We Have Answers

Can the SP3 fit onto any telescope?

Virtually any telescope can be adapted to utilise the SP3, however some like SCT's may limit features of the SP3 like the 360 degree rotator.

How come the SP3 focuser resolution is much lower than others?

The truth is your resolution does not need to be better than 1 or 2 microns, anything lower is not required due to your critical focus zone!

Why does the SP3 use Bluetooth not Wifi connection?

The design choice to use Bluetooth not Wifi connection for the SP3 was purposful as a device to device connection Bluetooth is simple and fast, easily compatible with mobile devices (smart controller for the focuser).

SP3 First look

The SP3 has not failed on both my cameras the curves have 100% delivered on the graph and in the quality of the star. The Esatto focuser was far more difficult to use and get right. The SP3 seems a much better thought out product, I do look forward to less clouds to run it more. Next step is to run it with narrow Band filters and see just how well that works. So far I cant see any problems with the SP3.
