Quote:By the way should one use an illuminated reticule eyepiece for all the mount alignments? Or is it sufficient to center the alignment star by "eye-balling"?

Quote: It doesn't have to be illuminated. What works well, especially with a SCT, is to have the scope slightly out of focus, then you can see the cross hairs against the unfocused doughnut - and with an obstructed scope there's a tiny bright dot in the centre of the obstruction for precise alignment. Don't change the focus.
