Somebody else asked that here a month or so ago and ZWO responded that one is in the works. But given all the problems posted here with the 5N, I'd be cautious. For what it's worth, I'm getting guiding corrections on my AM3 about 0.10 on DEC and 0.15 or less on RA RMS after tweaking settings according to the discussion here about AM5 guiding.
Relevant info is I'm using a 2600mc Duo for guiding on a 448 mm telescope. Total equipment weight is 7.5 kg and I have about 3.5 kg counterweights. Even though it's under 8 kg, the mount couldn't quite handle the load without the weights.
