I wonder whether anyone can recommend any type of significant USB3 cable lengthening option for cameras like the ASI174m please?
What length are you desiring?? There are plenty of 10'-12' USB3 Cables which will work well with any "high quality PC USB3 Port" (and not all are - unfortunately). Or are you looking for 30'?? 50'??
I have had no consistent camera connections using various good quality passive and active USB3 cables.
Again, are you sure that your Laptop USB3 is up to the task?? Have you tried throttling-back the USB3 via the ASI Driver??
I'm trying to avoid use of a 'headless' mini-PC mounted on the scope for the time being at least.
Considering the cost of many USB3 Active Repeater solutions, you might want to jump to a PC Stick or Mini-PC or NUC...
