Atik 414EX mono - Weirdness on images

[joecoyle]

Hi,

It's been a few months since I last used my camera - been waiting for clear skies in Manchester (a very rare occurrence )

I have noticed some odd triangular patches on my images, which seem to subside after 5/10 mins... is this moisture? Is it normal? Doesn't seem to do any harm, but thought I'd check.

Thanks
Joe
