I tried to center a guide star with an old 12mm
reticle...but I guess its not the one that was
mentioned on this list before. As to the 9mm...if you
mean the EP with the adjustable cross-hair- we also
have it..so Ill try it aswell
however...I started thinking about autoguiding with
our old ST-6, its a camera that we used long ago for
imaging, and I hope it'll b usefull as an autoguider.
p.s if you think I should stick to the 201xt please
let me know so Ill go the right direction.
thanks a lot for the help so far!
Assaf
