AstronomyUkraine Posted October 23, 2021 Share Posted October 23, 2021 Last few times I've been out, my guiding has been terrible. I put it down to bad seeing and the jet stream overhead at a whopping 54 m/s. Even so, the guiding was far worse than even with those conditions. I decided to strip my mount down, initially I couldn't see anything out of the ordinary, until, I started turned the RA worm screw by hand. It was jerking as I rotated it. I stripped the worm gear down completely, upon inspection one of the RA bearings had failed, it wasn't seized, but making a click, click noise. This would obviously degraded any guiding, so I just ordered a pair of high quality SKF 628's at 10 euro each. Quote Link to comment Share on other sites More sharing options...
MarkAR Posted November 5, 2021 Share Posted November 5, 2021 Cheap nasty bearing never did anyone any good. SKF are decent. 1 Quote Link to comment Share on other sites More sharing options...

Soon as I changed them the guiding improved dramatically. It might just need a little tweak on the adjustment screws to get it perfect. 1 Quote Link to comment Share on other sites More sharing options...
