    A couple of years ago, I wanted to replace my old VMA200 mount with something more modern.
    While visiting the Paris Astronomy show (RCE 2012) I noticed the Nova120. At that time, it was a brand new offering that I have not seen before, hence my hesitation to purchase
    I wanted to purchase a E.U product to guarantee the quality and ease of access to support in my own language. I checked the forums and heard nothing but good things about the Nova120 so I decided to purchase it.

    I have used enough astronomical instruments in the last 30 years to know what great quality is. The Nova120 coupled with the PRISM v10 and a CDK20 (508 mm) helped me pull off 900s unguided images with great ease. (Raw FITS File here). Payload of this setup is about 80 kg (160 lb).

    The dizzying slew speeds, excellent accuracy and painless tracking makes this hobby easy and enjoyable again.
    After using this setup for a year and a half, the only problem I had was rebalacing the gear after changing scopes. The superb electronics and software included make this tasks even more easier that just eyeballing the scope for movement due to unbalance.

    You can very easily watch the motor consumption and know where the unbalance is….that easy. I have so much data that it is becoming difficult yo keep up.
    I have absolutely zero regrets, this purchase has made everything easier: No summer/winter worm-gear adjustments, no guiding… just start imaging night after night after night.
