Great start Dazza
it's quite respectable actually!
Love the diary of frustrations and confusion, it will get better
On the subject of focus, bah! Bartinov Shmartinov, I have never used such a contraption
instead I focus manually via remote hand box (RoboFocus) while looking at a focus star on the screen, can take a few minutes to satisfy my analness for perfect focus going in and out but it has never let my resolution down once!
