Please give us more reports on field test. See how much mag can you bring
this scope up on moon/planets before it breaks down.

At 200x the star test looked quite good. A single faint, ruddy
diffraction ring, confirming its ED status, not a true color free APO
triplet.

How is the focuser? If you put heavy accessories behind and point the scope
up, does the focuser slips?

The focuser is smooth and backlash free. I had to tighten the tension
screw more than I would expect to get the friction right for a 1.25"
diag. Don't yet have experience with a 2" diagonal, but I would not be
suprised if a heavy load causes problems with slippage.
