Belt upgrade kit and procedure for EQ3-2 goto?

[GTom]

Instead of buying a new mount for my 90/600 apo, I thought I could reuse an old EQ3-2 goto mount I had for years.

Is there a reasonably priced upgrade kit that would turn this little guy into a photography-capable mount?

 

Noteworthy that it came with a solid steel tripod and I also have plenty of counterweights, no need for upgrade there.

The AstroGadget kits from Ukraine do everything you need for a fair price.  I installed one on my Vixen GP and instantly gained full GoTo features including ASIAIR and ASCOM compatibility and backlash free tracking.  Now my GP guides well and functions perfectly with the SynScan and SkySafari apps. 
 

This EQStarProEQ3 is the kit that fits your mount.  The AstroGadget Pro series kit worked so well on my GP that I am considering getting an EQStarProEQ3 kit for a CG-4 mount that I have recently acquired.   The installation process took less than ½ hour on my GP.  You can search the forums here and on Cloudy Nights to learn more about the performance of these kits.

Thank you, This one is full goto with synscan 3, but I'll keep them in mind for later.

Which one?  Did you link it?

It's a 10 years old mount, no link sorry. I am 500 miles from it ATM, can't post pics either I am afraid. Both axes are stock motorized and I recently updated the firmware (03.39.10, from here: http://skywatcher.com/download/software/synscan-v3-hand-controller-firmware/)

I'd need convincing that it is worth trying to upgrade the mount, given that it is already GoTo and has plain bearings.  If its existing performance does not match your ambitions and the APO scope, I'd say you need to invest in a better mount.   I use an EQ-5 Synscan for EEVA imaging with a 102mm achro.  The mount has a bigger weight capacity than the EQ-3-2 and has roller bearings.  Ambitious imagers recommend an EQ-6.

Investing I had already, carrying it is another question. The eq3-2 is super light, weighed 4kg's the other day. My g11 weighs about 3x that: still perfectly transportable by car but definitely no flight luggage issue.

Got some very interesting tuning advice here, will definitely try this cheap fine tuning before moving on:

You might find this useful. Not an EQ3-2 but I think the EQM35 is much the same in terms of gearing (and if not, you can work out the gearing you need from this)
