Hi Matt,
Phew, I am you confirmed my thoughts on the Lat setting, I was thinking I had to compensate for something else.....like dementia.
Darryl, funny you should mention halfway between Archenar and Acrux, because when I was drawing the lines on the first picture it struck me that the middle of the line between Archenar and Alpha Centauri was very close to the SCP, although a little low of it. I was going to mention this in the post, but a short instruction already had become a page and a half!
Unfortunately I don't have an illuminated reticle or green laser pointer, but in finding the actual position of Sigma Octanis etc, I attached my 11x70 binos to the scope using an adapter bracket and that helped me zero in on the spot in a view I was familiar with. This also means that I can get a binocular view of most other objects I target with the GEM mount.
Maybe I will try to attach my camera to the binocular eyepieces and see what becomes of that one??
