Re: #EXOS2 My RA on my mount is wiggling, Causing Star Trailing!!! #EXOS2


I have similar issue with IEXOS-100, there might be several reasons I suspect:
First is the periodic error due to the imperfection of the gears, it causes the rocking along RA.
secondly seems the tracking rate is slightly off but I guess it will take some effort to change it, but you can try tweak it a bit by setting the custom sidereal rate, +-2 to start with.
