Had a go at using my ToUCam for the first time last night, prime focus. All I could see was a very nice image of the secondary mirror, slowly drifting across the screen

As there was no Moon, and Jupiter already too low, I just picked the brightest star I could point at and hoped I'd be able to see something. I was just running the VLounge software that came with the ToUCam, all standard settings. Any beginner tips?
