Thanks for the kind words. Much appreciated. Alex, I thing 'relieved' is more the feeling now - it's been 6 months of issues with me or the weather since I got the gear.
The cold light of day has revealed that the video is actually a bit underwhelming. I didn't nail the focus and the gain is too low. Consequently the analysis software keeps losing the star. I've played with settings and now it doesn't loose it until during the event. I'm sure I will eventually get data from the video but it's going to be a wrestle. Meanwhile, I've attached a still from a test video when I got it right. That's the Jewel Box and I've found mag 11.2 stars in that frame. Equipment is: 6" f/8 acromat with 0.5 reducer on a GC-5 and a Watec 902H Ultimate video camera.
This how it's supposed to look.
