HEQ5 setup and upgrade questions
Posted 05 July 2009 - 01:53 AM
My second question on this mount is the SynScan upgrade. Apparently there are different models that can be upgraded. How do I know which one I have and can it be upgraded with just changing the hand controller or would it need the motors and boards as well? Mine does have the auto-guider port and the polar finder is illuminated.

The altitude T bolt issue will depend on what your latitude is and whats mounted and therefore where the weight is on the DEC bar I guess. at 51' lat. and with an 8" newt mounted I didnt have a problem. But after an upgrade to the scope I needed an extension bar on the DEC shaft to get balance. For various reasons I decided to dump the extension bar and get an extra weight unfortunately the change in weights and their position meant the weights on the DEC bar would foul the T bolt (I had replaced my T bolts anyway with better bolts from astro-developments).
I just ended up having astro developments run me off a special altitude bolt which is shorter than the normal ones. I could have machined the end off the old one but my access to machinery had been temporarily limited and I got fed up waiting. The ends of the bolts as you will know have a long tip thats rounded off to prevent damage to the tongue of the altitude assembly.
The Synscan handset is flash upgradeable after version 3 is my understanding. If you go to the menu which gives you the version number is should say something like H/C ver 3.12 - anything above version 3 is upgradeable. Older versions will need a new handset as far as I know.

Good news on the controller. Now I just need to find one cheap enough.

The two T bolts are different lengths. Switch them and you should be fine.
Thats weird - mine were both identical. I didnt like them anyway so swapped them out after someone I know had their mount messed up by the bolts bending.
