Celestron CG5-GT mount (tuned)

Hi everyone,
I have finally bitten the bullet and reguire a bigger mount for heavier payload. I was very reluctant because i need a mobile setup, but oh well.

This mount is 1 year old and the latest version of the CG5-GT and has the ball bearing equiped head, firmware 4.16 and steel heavy duty tripod. It has the wonderfull any star polar alignment routine, which is great for imaging.

In addition I spent a great deal of time tuning the mount by stripping the head down completly, cleaning, de-burring and polishing all moving parts. I then re-assembled the mount using high quality synthetic marine grease with PTFE. I spent hours optimising wormgear position to reduce backlash, whilst not binding motors.

I am a plant fitter/mechanic by profession, so i used my experience to get everything precise.

Unfortunantly i didnt run any PE analysis before and after but by observing the PHD graph it made a noticable difference.

The mount is in great condition and would suite anyone that is after a more back friendly mobile setup.

$800
Im located in Perth

The first 2 astro photos are unguided and using the hand controller polar alignment routine, which gave me up to 4min exposures.
The other 2 are guided, also using same polar alignment softaware.

cheers Jason
