It's a massive difference there !!!
What can you tell me about the values?

I'm moved to Guiding Rate 1.0X
Is there anything I can do about the Green and Blue bars from the Corr in the Graph? as in: indicator for me to change something?

Yes, now you can start lowering the minimum pulse on the right panel, I used 60-80ms.
Just try that.

set to 60-80
The RA RMS is still quite high while the DE RMS is much more acceptable.
When changing the pulse, big value change or small amount? ie: from 60 to 100 or from 60 to 65 ?

now we getting somewhere !!!!
I've increased the Proportional Gain from 133 to 266, on the left box which I guess is affecting the RA as the RMS has gone way down and staying down.


now at 1.27 RMS just a minute or two after taking the above screenshots.

In my case low numbers in the change does not affect, I need to change at least 20ms at a time.
But each setup varies.

Just one thing you did get lower RMS at 0.5x and lower exposure right?
Can you confirm the minimum pulse you have in the indi settings of the mount?

Just set set minimum pulse on right panel to 80-80 instead 60-80, and see what happens...

Here's the indi eqmod tab.


At the moment the Guiding Rate is set to 1.0X I'll change back to 0.5X and see how it goes.

You have the minimum pulse (ms) at 10ms, I left it at 50ms, that was recommend in windows eqmod too:

eq-mod.sourceforge.net/docs/EQASCOM_Guiding.pdf
at page 4

"EQASCOM always imposes a minimum pulsewidth of 50ms as it is not practical to accurately measure shorter periods."
I learned this one the hard way....

10ms is too low and the mount can't cope with the guiding that way.
Just try it please. At 0.5x and 1.0x

I've put to 50 ms in the indi control panel.
Not sure it has an effect right now, but up to that change from 10ms to 50ms the value RA RMS has gone quite down a lot...

It's looking much better now.

Just stop and start guiding after changing the value to see the difference. It should guide better.
Did you reset RA proportional gain to 133?

Current settings and results so far:




Thanks for the help, much appreciated.
Pretty sure I can achieve below 1 for the Total RMS now. Just need to carry tweaking...
