However, be careful. SCTs are pretty seeing sensitive and it may just be that you are seeing it in its natural state due to atmospheric factors. Check for concentric rings on both sides of focus on a fairly steady night (Polaris is good for this as it holds still) before you start tweaking what may not in fact need to be tweaked. If some adjustments are needed, make them very small. You don't want to be cranking those screws far at all.
