I'm trying to set backlash compensation on 2 of my scopes. As the temperature drops the focus moves IN so I think I would set the direction for backlash compensation to OUT. On the other hand I think SGP always focuses from high numbers to low numbers. On one scope the numbers go from low to high as the focus goes out. On the other scope the numbers are reversed - they go from high to low as the focus goes out. So, what should the settings be for each focuser. I'm assuming backlash will be taken up only when the scope changes direction.
Also, I'm assuming that I don't need to get the exact number of backlash steps correctly - as long as I put a number larger than the actual amount of back focus I should be ok. Is this correct? Thanks for any help.
