I tried connecting my Canon 20Da DSLR to the ASI Air Pro with a shutter release cable. I set camera communication to PTP , Manual, image RAW, noise reduction off, mirror lock off, and it still doesn't appear in the camera list. Is the 20Da Astro Camera supported?? Also I have 2 EAF focusers . 1 on my main Telescope and one on my Guidescope. Does ASI Air Pro support 2 focusers at once??
