After my ExploreScientific iEXOS 100, also wifi, I found this AZ GTI excellent: quality-price-weight ratio, very complete software. A little trouble all the same to make it run with SkySafari6Plus ... (I only got there once, but how? ...).
Mounted on a Rolleï carbon tripod, and on an EQ base, it easily supports my TS Optic 80mm (3kg), both visually and in photo, with a manufactured bar + 1Kg weight.
For the battery, a tiny Omega (€ 15) of only 4000 mh (with converter cable from 5V to 12V), is enough to power it over several sessions, amazing!
In addition, the SynScanPro app has everything you need for night-time SHOOTING (intervalometer, Time-laps ...), in my opinion, put in EQ mode, it buries the StarAdventurer from afar, on which I had made my choice beforehand.
Perhaps the tripod proposed by SW seems inappropriate, otherwise only happiness in terms of ultra-nomadism
