EQ8R-PRO poor guiding

[matija]

Hello!

 

My eq8r has been guiding rather poorly. The main problem is the huge jumps in the RA axis. I'm on asiair so I don't have PPEC. I'm perfectly balanced and very well polar aligned. I use a 240mm fl guide scope and a 485mc.

 

Ill attach a few images of my guide graph that displays the issue.

 

Any help is much appreciated!

So what driver is being used to control the mount….?

@Stuart1971 I use asiair and guide with the built-in guide software

So the ASIair has its own driver for the mount then… and you don’t use EQMOD or anything like that….?

If so then I can help, as I use the standard ASCOM drivers with mine

if you are getting spikes in RA, that usually means balance or stiction of some sort….

@Stuart1971 My RA axis scrapes a lot and loudly when slewing. Has this anything to do with it?

That’s not an easy question to answer, I have done mine on the DEC axis,  but you have the newer model mount, and it’s a different procedure….🤔
