Thanks Les.

I did some testing last night despite the not very good conditions.

Collimation took only a few minutes, with my ZWO ASI120 watching the defocused doughnut of Canopus and adjusting the two thumb screws. The long baseline between the adjusting screws and the 0.5mm pitch of the screws makes the tiniest adjustments very easy.
The attached image is from a 1min AVI using 100ms exposures, stacked with Autostakkert and stretched in AstraImage. I'm quite happy with the optics and tonight I will try to use a bigger sensor.
