Motor focus for ED100

[orley]

Hi all,

Current setup: scope in garden, laptop in shed. Me running backwards and forth tweaking focus on the scope and checking image on laptop. Legs weary, patience stretched.

Can anyone recommend a good motor focuser that I can use with my SkyWatcher black diamond ED100? Ideally i want to be able to tweak the focus from the comfort and warmth of the shed, preferably using the laptop. Distance between laptop and shed is approx 5m.

Thanks in advance,

Orley

Hello,

While your order is processing I was wondering (I'm just  a curious newbie bystander) would you share a pic of your setup and shed? In daylight of course

Worry not, found the answer myself...

Hope this is of use to others.

I made a focusser from an R/C servo.  It runs from a 9V battery with a speed controller - you can make the connecting cable as long as you need (within reason!) mine is 5m.  I can go all the way down to the tiniest "nudge" to get focus dead on.  Here is the link (ignore the first bit - its just my experiments!)  http://stargazerslounge.com/topic/91973-fiddling-with-an-autofocusser/?hl=+focusser%20+bizibilder

looks like that will do the job very well!
