HEQ5 mount basic operation question

Hello

I've recently purchased a HEQ5 Heavy Duty mount equipped with an Argo Navis (AN) Model 102B. I am trying to familiarise myself with the equipment in readiness for attaching my scope. So far I have successfully attached the

1) mount's handset - it is the basic unit sold with the mount that has options of 2, 8 and 16x speed settings and 4 buttons to control axial movement. On the side of the handset neither axial setting is set to reverse.

2) mount's power supply

3) Argo Navis

4) AN connectors to encoders
5) AN power supply


I have run through some AN menu options and can see that the on board battery has sufficient charge to ensure the mount's settings have been retained. I am stuck at the point of just trying to get the handset to move the mount. I have removed the side plate on the mount and I can see that when I press the buttons on the handset the gears engage as expected and both sets of cogs are turning appropriately. Furthermore when I have the AN menu set to MODE ENCODER the readings are altering as expected. However the mount is not moving at all that I can see. I've depressed each button for over a minute with the handset on 16X and unless the movement is glacial (my inaugural post's tangential reference to this website's name ), there is no mechanical response. I can freely move the mount by hand through both the Right Ascension and Declination axes when the lock levers are loosened. The pressure applied by the levers makes no difference to motor engagement. Any pointers or suggestions?
Thanks kindly
ANE

Hi, and welcome. Sounds like you have a EQ5, without the "H". This is not a goto mount, so the 16x is not a slewing speed but a faster tracking speed. It is still very slow moving so you would not detect any movement with the naked eye, but you would through the telescope eyepiece when centering an object.

Cheers Rick

Hi Rick. You're right it's definitely not a Goto mount or there wouldn't have been any point installing the Argo Navis. So I knew it would be slow. I just didn't realise it would be that slow on 16x. I hadn't mounted the scope yet and sure enough I saw the movement through the eyepiece once I did.
Just for the record it is an HEQ5. I've attached a photo of the badge. Thank you kindly for pointing me in the right direction, in more ways than 1! I'm hoping for some clear skies in the early hours tomorrow. Cheers, Michael

No worries good that you are on the right track, and I didn't know that HEQ5's came in a non goto configuration so I learnt something as well.
