Hi Richard.
to the forum!
Iridium Flares are great, very exciting when you catch a bright one.
The Heavens-above listing also shows you the compass direction (eg: South-East), I simply use that. And most times they seem to travel from south to north direction.
You will be able to use a starmap too. The hard part is catching them when they're faint.. sometimes you only see them when they get really bright as you were looking in the wrong direction
