I am using a UMI17 Lite harmonic drive with an Askar 65phq, a MeLe 3q mini PC for controlling and an android tablet for accessing N.I.N.A on the MeLe. I have a carbon fiber tripod (with sturdy 40mm legs) and use the polar wedge that came with the UMI17 Lite. All of this has travelled per plane at least four times.
Most important to me is the power supply. I used to use normal power banks from which I got 12V 3A max power per 12V USB - PD cables with additional 12V voltage stabilizers. That worked very well mostly …. until it didn’t once in a while. USB-PD is a bit finicky and it may just decide the power drawn is too little and it shuts down!
Now I am using a SmallRig VB99 V-mount battery which I access per D-Tap (no finicky electronics that may or may not think it shuts down supply, but unregulated voltage starting at 15V) routed through my 12V voltage regulators. Very stable!
It all depends on your needs! For me 416mm focal length is “deep sky” enough and I also use the exact same setup when I do “wide angle” mosaics with my 105mm lens on my Canon DSLR (instead of the Askar telescope). In all cases, I can (and mostly do) autoguide with a little 120mm guide scope.
The system is not “mobile” enough to be carried on the back on long hikes, though.
