Hi Kencas,
That rounds like a really innovative idea and well within budget
thank you for the suggestion. I'll look in to it
Hi Ray,
My 5D is a mark 1 which doesn't have live view so it's a case of take a shot, review it, adjust and take another. I am however using probably not the brightest star but certainly one of the brighter ones, generally nearest my target. I'm not 100% sure but it's likely that shot was Anteres.
Thank you for your input
