Two cameras with one connection to PC?

Guide camera connected to the imaging camera via usb (both Altair Hypecam), then fed back to the PC, via a single USB cable, any predicted issues?

I do this with two ZWO cameras, USB cable runs from guidecam (120MM) to USB port on main imaging camera (071MC Pro), then USB from imaging camera to laptop.

Only things I would be careful with is making sure that your software is trying to connect to the right camera. I had an issue where PHD2 was connecting to my imaging camera and APT was trying to cool my guidecam. Gave me a bit of a panic when it disabled my cooling the main camera and watching the temperature spike for a couple of minutes while I figured out what happened was not fun.

Easily fixed by making sure the right option was ticked on connect equipment on PHD2 and shift clicking on connect camera on APT.

Thanks for that. Seems like it should be fine.

Use. USB hub

[Xoc1]

I am using a USB hub to connect a couple of cameras - I am using a USB 3 Startech Hub with a 12Volt power input, which I made up a power lead to work off the 12Volt supply that I use on my Scope to power a DC - DC voltage convertor for a DSLR and for a 12Volt cooling fan  & a planned powered focusser.

Using a powered hub can avoid any power limitations from your USB port.
