NEQ6 Performance:

Upgrading the worm gear bearings to Hybrid-ceramic items and belt-driving the motors substantially reduces backlash and improves periodic error. Tuned mounts run typically at circa 3 arcseconds RMS, and can be autoguided to consistently perform sub-arcsecond tracking, especially when allied to a QHY Polemaster.

We have HEQ5, NEQ6, AZEQ6GT and now EQ8 Reference mounts that are utilised to constantly improve our tuning methodology and demonstrate the benefits of enhancing the mount.

Here is a customer supplied PHD graph of one of our EQ6 Mounts. Other customer supplied examples are available upon request.

Work includes:

Each EQ Mount is examined externally for any damage and owners are notified for any extra-parts (replacement Sky-Watcher EQ bolts, for example) if needed. We photograph dis-assembly and reassembly of key components, and video before and after with a sound check that creates a unique sound signature for each mount.

With a belt drive upgrade the mount is up to 10dB quieter and removes backlash.

The Mount is stripped back in both axis to component level, inspected for damage or wear, and degreased. Owners are notified if any extra-parts are required or upgraded by request.

Cone Axis bearings are degreased, checked for wear and ultrasonically cleaned and re-lubricated, as are the bearing cone surfaces checked and cleaned in the mount.

All external threaded bolts on mount and tripod (if supplied) are degreased, ultrasonically cleaned and re-lubricated. 

Motors tested and gearboxes checked*  (*where applicable).

Mount is reassembled using upgraded greases and oils which operate in all temperatures from -25ºC to +50ºC (we use them in our Export Service and our own products so have been tested at these temperatures!).

The Mount is then bench tested and adjusted to remove backlash and to ensure operation of mount.

GoTo Handset and Mount is checked for Firmware updates and updated with latest code as required and tested for operation.

Free fitting of QHY Polemaster adapter if purchased and camera test to ensure correct focus and operation.

In the case of axis repairs and tuning we carry out a load test on every mount with either an 8 inch reflector or 100mm f9 refractor - or 70mm refractor for smaller mounts, and adjust worm back lash to dial out as much movement a possible so to ensure the mount is performing as it should under real-world conditions. 

Mount is then readied for shipping/collection.

The mount is videoed/photographed during evaluation, disassembly and rebuild, with a soundwave check to confirm drivetrain signature. All work carried out is now covered by our 2 Year limited Warranty.
