Thanks for the comments guys
appreciate it! :-))
I was doing the 'manually focus, then take a test pic and check it by zooming in on back opf camera lcd monitor, keep repeating till correct, method, which worked 'ok-ish' for me with tripod shots recently, - but Stewy was getting impatient as i was up to my third attempt at getting focus right by then (i also had NR on so was making it even slower)
and we were only messing around as a test at the time, and he said that'll do 'lets go' hehe -
But I noticed how good/sharp your comet shots were Gary, so your method obviously works well - and as you say Geoff, Leons shots are great too - so his method obviously works well to
seems to be a few ways to go
its nice to have choices
