Orion Accufocuser used on a Skywatcher Pro 120ED

[jhbsky]

Good People,

need to get a electric Focus option for my Pro 120 ED refractor.

I was wondering if the Orion Accufocuser will work on this scope.

I've seen it used on a 80mm ED.

There might be other solutions that i may not be aware. (JMI  have a solution) but the Orion is  nice and cheap.

Cheers

Also does anyone have an app that makes skies clear ( its been rain and clouds in Johannesburg since late October)
