Whatever I do, I cannot get the inner reflection into the centre of the focuser so cannot get concentric. Followed astrobaby guide, centering focuser, adjusting with the main screw on focuser, secondary screws and using chesire eyepiece.
The crosshairs of the chesire align with the primary centre circle marker.
Have attached photo but shows worse than what it is.
Who wants to come over and HEEELLLPPPP

Hi Kon. Don't panic. I think that is right where you have it . That is showing the offset pattern of a fast scope and and if you look at astrobaby's instructions down the bottom she has a picture ( and a diagram) of this.
