Could I put a 3x and a 2x together and have a 5x barlow? I would just go out and try it, but it is cloudy. Thanks.

Together, a 3x and 2x Barlow would be the equivalent of a 6x Barlow, not a 5x Barlow. It can be done, assuming your focuser has enough travel to bring your eyepieces to focus.

I use the TeleVue 2x and 3x barlows on my MN56 Mak-Newt for prime focus webcam imaging. If you have enough focus travel, it should be fine. I found the image too dark for a 26mm eyepiece. I use the eyepiece to center the image for my webcam.
