Full stripdown and rebuild of the EQ6 R PRO Bearing replacement and hypertune. Sky Watcher EQ6 R PRO stripdown and rebuild, Hypertune. Follow me while I work through the complete job of hypertuning your EQ6 R PRO. This mount is almost identical to the Orion Atlas EQ-g and the newer Atlas II www.bearings-online.co.uk Now a link to a complete kit of the bearings needed - https://www.bearings-online.co.uk/bro... 6 x 6008 2RS1 deep groove roller bearings 1x 30206 tapered roller bearing 1x 32208 Tapered roller bearing 4 x 608 2rs - these were the bearings I used but I have told the correct replacement are the metal shielded 608 2z. The ones I removed were metal shielded like these. The 608 rs are a higher quality bearing to the 608 2z and I personally have had no binding issues using these although another user reported he did. Other hypertuning services like ( https://www.deepspaceproducts.com/pro...) use the plastic sealed bearings as I did but I wanted to share what I was told so you can make your own choice. |

A total rebuild would be a last resort if you’ve exhausted every avenue and can’t get your mount to behave with reasonable performance after performing some basics with worms , belts , balance etc…. Plus with a total rebuild you really need a garage workshop area to perform the task with a bench , vice , quite a few tools etc… and a reasonable level of mechanical knowledge.
Dilshan’s images are excellent , even Star shape is good considering +2000mm focal length and with his guiding around 1 arc sec.
I have 2 of these mounts purchased nearly 18months apart , located at two different sites and have performed a mini tune plus rebalance as per my original post.
Both mounts were guiding around 0.80arc sec (average) or higher , depending on conditions using PHD2 hysterisis algorithm.
Now after the mini tune to reduce backlash , a rebalance and using the PPEC algorithm they both are capable of guiding as tight as 0.45 to 0.50 arc sec with minimal backlash and with payload up to 14.5 kg. ( Average 0.60 to 0.70 arc sec )
For the mini tune all you need is 2 Allen keys and a Philips head screwdriver. I’m sure if this is done as best a possible , the mount will be performing considerably better. I have 2 of these mounts which have benefited greatly from such a simple task
