I use my ASI290MM for guiding and it works well, although my focal length is a lot shorter

Even so, the difference in seeing is quite noticeable, both in the size of the stars and in how PHD2 responds. My mount is a mere modded EQ6 but it's a consistent performer, unlike the seeing.

And the 290 often shows the target object in the guide image. I was most surprised when I had one of the Leo Triplet front and centre in 2 second subs.
