Just a quick update - I ended up buying the Giotto 120 panel. I am not using ASCOM/USB, so it's really handy to be able to adjust it via wifi using the browser on my mobile.
Did couple of quick tests on the uniformity following the instructions on CN from John Upton (
https://www.cloudynights.com/topic/8...#entry11849571) and the results I got were 0.8% and 1.17% non-uniformity. Used different brightness and exposure between the two tests, so this might explain the difference. Will do some more testing down the track. But pretty happy with the results.
