Hi Rob you will like the kit it is well built .
we have had bad weather here but we found ourselves as we went past the mount all setup we just had to turn it on change the speed rate to 9 and slew around tilted the scope 10" Newtonian past zenith and all around the place we just could not believe how Quiet it is and it's responsiveness to the key press's with the direction keys.
A well planned and well constructed kit.
Thanks Dave.

I've ordered an NEQ6 kit off Dave and was pleasantly surprised to find the prices for residents outside the UK are 20% off website quoted (no VAT) - about $211 AUD delivered.
(I was beginning to think Dave might just like Aussies )
Thank you Rob, Steve and Alistair for ordering the kits.
They'll be sent on Monday and should be with you in about 9-10 days.
You should receive an e-mail when dispatched with the parcel reference number.
That number can be entered on this web page and it will give deatils from when the parcel arrives at Australian customs. http://auspost.com.au/track/
Thanks again , Dave.
Hi all video using the NEQ6 Belt Mod from Dave and our 4 way Bluetooth Module with EQMOD Stellarium Scope And Stellarium. This video was done with a ipad.
The 4Way Bluetooth Module boxes are still not back from getting Manfactured .
We have No pics of the module there are only 2 Prototype boards the rest of the boards will be made up after testing is done the boards get made in the USA.
Link below to the video on YouTube .
Yes we did, results are NO backlash very Quiet, No rubbing of belt on mount casing.........Prior to the install, I had a friend of mine, who is an engineer, check to see how concentric the pulleys were, We did that with the Pulleys ON the worm shaft/motor for both axis, and found them to be perfect........Checking them on the shaft is the only real way to determine, how concentric they are.

And also in our Merlin and allview they plug into the mount and get there power some mounts are different so we make them different.
Anyway back to the topic how did your belt mod kit go did you manage to do testing before and after the install of your belt mod kit.?
Ok, I understand that, but still cant understand why you need to plug into the HC, if your going to use astro programs, why not just go direct to the mount?

Thanks for your suggestion
Interesting thread given my (now for sale) EQ6 was modified with a belt system made by Astromeccanica. I can't comment as to whether it was an improvement over the original setup as I purchased it in its modified state.
Basically All It does is get rid of gear noise and gear backlash not much else,
The above is not correct.
My findings are that is does a lot more than you say.
Both mounts I have fitted belt kits to , HEQ5 and NEQ6 have shown significant improvement in peak to peak periodic error.
The attached shows a before and after comparison for a HEQ5.
The transfer gear was a particular problem.
Look at how subsequent worm cycles don't overlap.
The max peak with the gears is +14.9 to -7.8 arc sec that has no chance of being improved be periodic error correction.
With the belt fitted the peak to peak was reduced to +6.1 to -7.4 and is now cyclic which can be further improved by periodic error correction.
The mount was nice and quiet too.
Well of course it does, replacing the gears with the belt is going to remove any concentricity problems the gears may have had, Rather obvious I thought

My primary objective is to improve pointing accuracy and repeatability as I'm working on automated imaging and I need pointing accuracy to be decent for plate solving to work consistently and as Peter's mentioned below, it would improve as well, or at least i'm hoping it would. Will need someone to test it out.

The performance of the mount will be around the same but backlash is essentially eliminated, this has a large positive impact on pointing.
