argo navis 90 degree alignment
Thanks Eric for your later post plus the link to Gary's post - feel relieved.
I bought an illuminated reticle eyepiece just so I could be sure I was centering my 2 stars dead on but then started to worry about the initial 90 degree alignment. Will put your advice into practice on the weekend. Haven't really given my argo navis set up much of a test after buying it sometime ago but not being able to get back to observing until very recently.
