Last night i had strange thing in relation to auto focus, it failed. It didn’t Analyse the stars. When shoot in the whale galaxy. when slew away to other object ist seem to work. i was wonder what cause is, i expect because there where not bright stars to trigger star Analisys. how to overcome this kind of situations.
My star minimum diameter for my canon 40d at 1x1 pix 6, should this be lower or high? The exposure time it is now 10 seconds
