Skymax 180 focuser
in Discussions - Scopes / Whole setups
Posted
I've been looking and looking for a solution to this, but have been drawing a complete blank. I'm wanting to improve the focus on my Skywatcher Skymax 180 Pro - out the box it's just a knob to move the primary mirror (which I guess is standard for catadioptrics?), which is quick but coarse. So what do I mean by "improve"? I mean the following:
Simple! Yet there just doesn't seem to be a solution ticking those boxes out there for the Skymax 180. I could add a Crayford, but they're either fairly expensive and very heavy, or outrageously expensive and still quite heavy. Other SCTs have the option for something like a JMI Motofocus, but they're not available for the Skymax 180 (and for what they are, they do appear IMHO to be quite pricey anyway). I could put a peanut butter jar lid or clothes peg over the focus knob, which is cheap and would certainly improve fine focus, but doesn't get away from the shaky touch problem.
Has anybody found the answer that I'm looking for?
Cheers,
Ian
