Portencross castle - Old and New
One of three defensive castles built on the outskirts of West Kilbride and one of only two still standing, Portencross castle sits above it's own small harbour.
-(Cheers! Thank you all very much.
Luckily the 18-55mm lens that is prettymuch standard on canon SLRs is just wide enough to get both the pole star (which my Dad calls the nail of the heavens - does that make the world a cathrine wheel?) and something which is attached to the ground into the frame.
This photo was made up from 163 seperate 30 second exposures all layered on top of each other in photoshop 7 using the lighten blend mode. Doing it that way cuts down on thermal noise as the sensor doesn't get as hot if you were to have it running on bulb mode for a similar time.
Unfortuantely my home made cable release wasn't working for this first attempt (I blame bad workmanship) so I had to take them all manually pressing the shutter button every 30 seconds for over an hour and a half. Luckily the tripod didn't move.
You can see an artifact of this process in the bottom left corner when the Scottish Air Ambulance flew through the frame and left a trail broken by the time it took me to react to fire the shutter again!
I've now fixed my cable release and added a 2 way switch in parrallel with the original button so that I can now leave the camera to do its thing without it requiring my constant attention. I will try and do more of these when the skies clear and hopefully get the object in the foreground exposed better. I also hope if I'm able to move about I won't get quite so cold!)-
