Ok update.
I don't have the advanced focuser, I didn't think I did. I can achieve focus with a 2" diagonal. I had a quick peek at the sky last night...balancing the scope on a table

. From what I saw...great, absolutely no fringing crisp views, although that was only on 40X.
The focuser works great but there does appear some issues with the
thumb screw & keeping accessories square to the
draw tube.
I have ordered some thumb screws from
Scope stuff and will add some extra around the draw tube collar. This should fix this issue.
I have measured the thumb screws and they appear to be M4 x .7 threads. Lets hope I measured them correctly as it's difficult to tell.
I also ordered some M5 x .8 thumb screws to add qty 3 to the finder. This may fix the finder but I suspect I'll have to buy a
better finder holder.
So far it's a good experience with some little warts. But for the price...
