AstronomyUkraine Posted April 13, 2021 Share Posted April 13, 2021 Tomorrow I will be picking up an EQ6 Zero Backlash Worm Mount from the PO. This nice piece of engineering from Rowan Astronomy in the UK, replaces the RA axis on my EQ6. My guiding is not that bad, on a good night I'm down to .6 RMS, on a poor night it can be as high as 1.0. Although not terrible, it can definitely be improved on, and is a cheaper option than buying a new mount. An Ioptron with the ability to carry the same payload is over 3450 Euro, the RA replacement is £285.95, so it's a lot cheaper alternative if I can reduce the RMS to under .50. The RA replacement, is a spring loaded device to minimize backlash on the worm. The job is very straight forward, I have already done the belt replacement, so I know how it all comes apart, and I'm only stripping down half of it to do the upgrade. 4 Quote Link to comment Share on other sites More sharing options...
