A bit of fun with the stars last night

Bizibilder decided to have a play with some simple star trails last night.  An old 50mm f2.8 lens from his old film camera was put onto the Canon 1100D (with an adapter!) and carefully focussed.  The whole lot was held on a conventional tripod.  About 30 x 10 second exposures were made of an area in the constellation Cygnus.

One process was to assemble all the pictures as “star trails” – just look at all the different coloured stars!


Then the same pictures were stacked on top of each other to give this:


And finally a piece cut from a star atlas to show what’s what:
