Quote:...When fully collimated, while looking through the collimating eyepiece if you rack the focuser all of the way out the very bare right edge of the mirror is cut off in the view. It just takes off enough of the view to remove sight of the edge of the mirror clips on that side. When racked in the whole mirror is visible.
Quote:I just don't like losing that small sliver of mirror when racked out. I have heard reference to the focuser needing to be square. Is this the issue I am experiencing? Do I need to shim the focuser on one side?
Quote:I dont think that is an issue. When using a sight tube the center of the mirror is directly under the crosshairs.
Quote:...When racked in all appears in the sight tube aligned and visible.
Quote:...When racked all of the way out the edge of the secondary...the upper right edge to right middle is slightly out of view by a hair, but the sight tube stays centered over the secondary and the primary center mark.
