Almost a 5 but not quite
For the price it's hard to beat this artificial star. One drawback, to select the size star you want requires the others to be blocked off by a little magnet shield. It is very weak and I have lost it in the grass twice already. Luckily found it...

Excellent Collimator

Bob's Knobs in Australia.
Fitting these knobs to the scope was easy.Just one at a time so the mirror was still held in position. Collimation of any scope is now very easy.No trying to find the right screwdriver and adjusting in the dark.
