Is there any easier way to get finer focus control on my scope than the tractor steering I have now?? without using a laptop?
I hope someone has an answer for this one.

Hi Chris - the 10:1 crayford style would be the logical way to go if procurable; but with the rack & pinion on an SW 150mm achro not giving me that option, I purchased an electric focusser for it at just under $100.
This makes a profound difference to the focussing operation of the scope - certainly superior imho to the manual 10:1 crayford on my dob; though you can of course convert those to electric too!
At "finest" rate of adjustment the ability to focus to an absolutely razor-like degree is great; with the added bonus of it being hands-off, avoiding scope vibrations.
If interested in going this direction, just check first to ascertain if the SW r&p's are the same for reflectors as refractors.
Cheers, Darryl.
