I have just gotten my Asiair plus and I have been trying to set it up. I am using a usb 2.0 cable with my camera which is an 1300d or rebel T6. When I am trying to take an image there is nothing on the screen except rbg noise I have tried many ISO settings and focusing as well taking photos in other parts of the sky, but all I can see is noise and grain. What can I do to be able to get clear photos of the stars?
