New compact camera tracking mount

Great report and comparison.
I have to agree with your view that the polar alignment is an issue with the Nano. The sight hole is difficult to access and just not practical to use.
With some iterations on my balcony, with no north view, using the mobile phone as tool, I have got it to track prety well for planetary observations with my telescope. I think the easiest way would be to adapt the Polaries's alignment tool to be used with the Nano. This is probably the way I will go.
The tracking itself is very good and smooth so there should be no problem tracking longer focal length when properly polar aligned.

Have you looked at Toast-Pro? Maybe too expensive for the U.S. market.
I had a chance to take a look at Nano Tracker at PATS. It is quite compact.
I'm considering when Hutech starts taking order.
I took a few pictures at Hutech Booth if you are interested.

while the TOAST Pro is +/- 7" periodic error, 150-tooth 83.5mm wheel.
the TOAST Pro is about $1300 USD. Pretty expensive, yes. That's Tak Teegul level. Probably better PE though.

I checked out the "Toast pro" at Kyoei, at the time I decided to buy the Nano. It seems to be well made with a nice finish. But it is quite big and heavy, on the other hand it can certainly carry a lot of load. The price is definitely on the high side, as Orly already mentioned. For that money you could get a small GEM that would do an equal or better job.
Thank you for the images of PATS some nice equipment, I noticed they showed the same Nano/Borg mount combination that I am using

Since I have no view to Polaris an optical solution was no option, so I decided to adapt the "Polariemeter" Vixen sells for their Polarie on the Nano.
I installed a flash shoe that is normally is used to fix an external photo flash to a tripod. One has to be careful to align the shoe as good as possible to the polar axis... not so easy.
So the flash shoe on the Nano Tracker looks as follows...

However my alignment was quite good so I could easily track Jupiter for several minutes at 120x without correction. With some fine an improvement would certainly be possible.

The GRS leaves the scene on the right side of the planetary disk and the moons Ganymede, Io and Callisto are visible from left to right.

That is some very nice work indeed! I'm tempted to put your combo (Borg Alt-Az + Nano or Polarie) on my acquire list for my FS-60C travel setup!

The FS-60C should work perfect with this combo since it is shorter than the FS-60Q. I find my setup to be on the limit of stability especially imaging planets at 1500mm focal length. The tracker is not the problem but using the balhead of the tripod to adjust the latitude angle.
I am considering adding an angle plate, which would bring the center of gravity to the middle of my tripod. The setup is shown on this website:
