Weather in Essex has been horrible for months. The promised clear sky's last night didn't materialise so I could not test under night conditions. However, checking the core software Change Log it does mention that the latest version resolves a "Horizon connection issue". This sounds positive and yesterday's daylight test was encouraging.
To be frank, I initially had trouble with the original Horizon's rather flimsy micro B USB connector. Atik promptly replaced that under warranty with a regular USB B connector. However, I discovered that if I ever used a USB3 cable longer than 1.8M I had connectivity issues despite using a quality Tracer 12v 22Ah battery. But it all worked fine with a high quality shielded 1.8M USB3 cable until core software version 5.0.0.4, which I believe was when Atik first attempted to embrace SharpCap and Sequence Generator Pro with a CMOS camera. After that, Infinity software repeatedly started to crash, notably soon after initial connection.
Thinking I might have USB power issues (which I have encountered before), I did experiment with active cables and powered hubs without much success. Interestingly, things did improve after switching from three seperate 'bricks' to a single 240v/12v 10 Amp (120 watt) AC/DC adapter, now powering camera (circa 24 watts?), focus controller (24 watts?) and my Intel NUC (65 watts?). Having access to slightly higher wattage than the aggregate rating of their individual 'bricks' does seem to have benefited all devices. Frankly, I am wondering if my original Atik supplied AC/DC adapter was a little short of watts to power bith it and USB3 cables? But my rig seems to be thriving now and a few spare amps won't hurt.
I progressively tried each new incarnation of core software in daylight test. It is fortunate that the weather has been awful, else I might have been fairly angry, as none have worked well in Infinity, albeit improvements were noticeable in Sequence Generator Pro. However, the latest version 5.0.4.6 does seem to be encouraging in daylight test. Just need to get outdoors again!
