Focusing is tough!
I just went through many hours this weekend trying to get my Stardot cam focused after ordering a new lens (auto-iris varifocal 4.5-12 mm replacing the stock manual-iris 8mm lens). I had the laptop up on the ladder with me, but dropped it once (luckily no damage). I was having trouble getting the entire image in focus. If the center was in focus, the edges might not be. I had a Stardot technician on the phone with me looking at the image as I tried to focus it and giving me some tips. I ultimately got to a satisfactory image, but not the perfectly crisp one I was hoping for. They said I could send the camera and new lens back to them and they would re-focus it for me for free but I would need to tell them the focal length I wanted - I wasn't sure of a convenient way to describe that to them so I just did my best.
