I need to get a hold of a star map or image of the position of the stars over Liverpool on the 12th of August 2013, around mid day if possible and was wondering if anyone could help me as I don't have a clue where to start.

Or Even better does anyone have pictures of the meteor shower that happened then? I can't find any taken locally

Don,t know if this is what you are after, scroll down to 'The mornings of August 12th and 13th: midnight to dawn'.

Just found this.
Composite image capturing a night under the cosmic rain – aka the 2013 Perseid meteor shower – on Lindisfarne off the northeast coast of England.

if u download a program called stellarium , you can log your postcode and rewind/fastforward to a specific day/time

Jabber's suggestion of Stellarium is a good one. A warning though.... it can be be a great absorber of time! My son works at the Royal Observatory in Edinburger and says it's one of the best sites to use.

Awesome thanks everyone you've been a big help
