Your light shroud system seems interesting and easy to make.

If Sky-Watcher is going to be available in the US, be prepared to see a lot of them. Here Sky-Watcher scopes dominate the public outreach things I have attended. No wonder, these scopes are well build (for mass market), hold collimation, are light and cheap. The control tension handle works great. Just as an example, my 6" SW Dob have no problem keeping its position even with the 24 Pan and a 2X Barlow in the focuser and with the Telrad and the optical finder on. From what I’ve seen, the 8 inch collapsible seems also well thought out and well built. I usually prefer buying whatever stuff from local producers but this is just too good for the price. My next scope might just be another SW.
