About this product

Model:  aok_ayoII_mount

New upgraded AYO II Alt-Az mount from AOKswiss. 

This is the mount other Alt-Az mounts want to be when they are grown up :-) 

Built in Switzerland the AYO II is the combination of over 15 years of development and refinement. If you like engineering you will be impressed! 

Beefier than it's predecessor with a more robust axle bearing for greater load bearing capacity, but the weight remains the same. 

Quality bearings provide easy smooth adjustments without judder or hesitation and the friction / resistance of the bearings can be adjusted individually via two large knobs. 

With a non-marring Vixen-style saddle clamp on one side and the ability to attach either a Losmandy-style or Vixen-style clamp to the other, the AYO-II will accept two telescopes mounted together for twice the fun! A counterweight can also be fitted to balance a single larger telescope. 

How big a telescope can I use? 

When used with a GOOD quality tripod, you can mount up to 8 kg on either side without need for a counterweight. This means, say, a 4"-5" refractor can be handled with ease. For larger / heavier scopes we recommend the use of a counterweight bar and standard counterweights, with these in place it can handle up to 12 kg. 

Which tripods can be used?

The AYO-II base has a 3/8" thread for attaching to most photo tripods (heavy duty) and, after unscrewing a cover, a threaded M10 (metric) thread enables use with tripods from Celestron CG-5, Skywatcher EQ5/HEQ5, the Meade LXD75, Vixen GP and Vixen Super Polaris mounts. Or, if you are wanting a tripod that looks fantastic and is warm to the touch, consider the excellent Berlebach Uni-18 and Uni-28 tripods made from Ash wood (Please select the HEQ5 version). 


  • Height / Width: 244mm x 207mm
  • Weight: 3kg
  • Recommended Telescope Weight without / with Counterweight: 8kg / 12kg
  • Recommended Maximum Telescope Length: ~1200mm

NOTE:  We do our best to keep stock of AYO II mounts but each one is manufactured, with great care, by one man so during busy periods they can take several weeks to source.  Please be patient :-)

A great alt-az mount
Wednesday, 23 May 2018  | 

I bought this mount for my Takahashi FC100 DF refractor and Berlebach UNI19. The mount can support it with easy, with minimal vibration damping at high magnification. Axial movements are smooth, with no sign of backlash. Essentially, moving the AYOII is like moving a high quality dobson mount.

For detailed measurements regarding the connection with the tripod, I contacted Beat (the designer of the AYOII) at AOK, who was very helpful.

Finally, FLO provided me with a great service, from email updates about crafting times to shipping.

Would I buy one again? Yes, for sure!
