The key question is how accurate are the mirrors.

I read one post on the net that quality checking of mirrors (not sure what type of scope and not necessarily these at all) was simply a guy putting the mirrors on a wall and shining a torch at them from a distance and then checking if they passed or not!

So I would want to see some images from them. RC optics are hard to make and Star Instruments have been making 1/24th wave mirrors for a long time. I believe it takes a long time. I know the Chinese industries pay their workers practically nothing but even so it takes skills and I doubt they have these. Not that they can't learn but it may take a decade or two.

Greg.
