Re: HEQ5 Rowan belt mod tutorial
I just started using my HEQ5 a few months ago.
It has about 3000ms of
I am definitely interested in doing the mod, but seeing that it will invalidate the 2year warranty, I plan to run it for awhile to insure that the mount is sound.
Really enjoying the HEQ5 so far. I usually get sub arcsec total rms error in PHD2. The worst error that I’ve gotten so far is imaging the Rosette Nebula (at the celestial equator) is 1.12 arcsec which I was happy with.
If you don’t mind, can you post your first impressions of the mount performance before and after?
Thanks a bunch for the tutorial Martin!

Re: HEQ5 Rowan belt mod tutorial
I would say that the tracking is smoother, even though I don´t have any guide graphs or values from before/after. I find it to vary a lot between evenings anyway. But what I do know is that I no longer have these sudden jumps in the tracking that I sometimes had before. Probably because the gears kind of stuck to each other. Also, backlash has been reduced.Juno16 wrote: ↑Wed Dec 08, 2021 11:23 pm Thanks Martin!

It has about 3000ms of DEC backlash, but PHD2 backlash compensation handles it pretty well.

Thanks a lot for the video and the post modification results.
The mount is quite noisy when it slews and I have also heard that the belt mod really quiet’s things down.
Very much looking forward to doing the modification!
Much appreciated Martin!

Re: HEQ5 Rowan belt mod tutorial
Yes, definitely quieter.
Luckily, my mount is pretty well behaved. I can wait a bit until things seem sound with the new mount.
I saved your video for when I do the mod. Very well done!
Thanks again Martin!
