Brilliant bit of kit
12 June 2022  | 

This is probably the most impressive bit of kit I have bought in many years.

The engineering is brilliant. The build quality is of a very high standard.

The stepper motors are mounted in very substantial cases with holes pre-drilled and tapped for easy location.

Although the system is designed for an EQ5 it can be used on many other telescopes with a bit of ingenuity as the worm gear ratio can
be set in software from 1:100 to 1: 1300. I am using the drive system to upgrade a Grubb Telescope built in 1872!
The cables for the motors, cleverly use RJ45 internet type connectors,
which are easily available in any length and are so easy to connect and disconnect.

The interface has an ST4 Auto-guider port, which is provided with a simple handset with NSEW and rate controls, so the drive kit can be used, stand alone,
without a PC or Mobile phone.

The interface has both USB and WIFI connections so can be controlled by ASCOM programs such as EQMOD and by other planetarium programs.

The interfaces are simple to use .

The most impressive feature for me was the SynScan Pro app on my I-phone, which was installed effortlessly by scanning in a QR code provided.
No complicated lists of instructions to follow, just scan in the QR code and you can control your telescope from the phone in a few seconds - absolutely brilliant!

I needed some extra help to set up a non-standard gear ratio and an email to Asterion in war torn Ukraine got me a solution in 24hours, so just amazing service

In summary, a very professional bit of hardware with very impressive user friendly software and excellent technical support.
