What a day today, you should have been there at Tailbrige. When I got there it was a nice day, wind too strong so I hung around for a while.
Then wind dropped, good you might say but it started to rain. Never mind stiff upper lip and all that. Rain stopped - excellent - it started to snow.
Twiddled my toes for an hour or two, snow stopped, wind stopped, fog came in down to the axels. Went away to find a very high cliff to throw my self off??

Just goes with the territory Colin, if your opening the body to the atmosphere you get particles in, totally unavoidable unless your in a grade A clean room or the likes. Cleaning the sensor is easy in the house with a special tool but once in the field its just a chance you have to take changing lens that some thing dont get in. However any dust specs like you notice are very easy delt with using photoshop, just didnt have time for this first attempt with the lens.
PS
A CCD camera is a very specialised camera for astrophotography, I have a Canon DSLR.
OK I actual meant CMOS sensor if you want to get picky but a CCD sensor isnt just astronomy as CCD is the name of the sensor in my konica minolta Dimage Z5 and it is quite easy to prevent dust in your camera in the field if you are carefull enough when I go to airshows I change the lense around 80 - 100 times my 400D i have never had dust spots but my 350D eventually you do get some. And I apologise for editing your photo it was for illustrative purposes only. I will remove it immediately.
