Hy,

FWIW, I rarely get guiding working that well either (I use an Atlas Pro, which I believe is pretty similar to the HEQ5 pro, though not sure).
Some of it depends on the seeing and the sky position of your target.
I find, though, that using the GPG RA guide algorithm helps me.
Are you using that?
BTW, GPG RA guiding resets every time you slew, and it can take 15 minutes after a reset to get to its optimum performance.

I have had good guiding, around 0.5", albeit under dark rural skies while on vacay, so its frustrating
not to get close to that. I use the GPG RA with major period set to 638 s (found on another post somwehere)
and tried without noticeable improvement by toggling estimate period. I will try a longer settle in to reach
optimum.

GTG,

Without checking every thing, no more than 3KG or 3.5KG I would say.

my SCT rig is much heavier but I hope to improve guiding after removing the guidescope and
replacing with a ZWO OAG that is coming in today. I would have thought with such a light load your guiding
would be much better. A WO GT71 is also coming today and I am keen to see how guiding that scope
on the HEQ5 works out.
