Sorry Ron,

'ED' as in ED80, ED100 scopes. They come standard with Crayford focusers which can be adjusted to aid in collimation (if ever needed)

It doesn't help with objective lens collimation though.

1. ED80

2. lines showing the screws that hold the focuser in, which you loosen to collimated then re-tighten.
