Hi, bit of an odd question I know but - the camera's night vision is too good for what I want :)   I'm using it as a sky camera. It's looking at the stars and of course the weather. The night vision is such that when the sky is very dark and covered in bright stars to the human eye, it's a very pale grey on the camera ... with the stars hardly visible. 

My question is, is there any way to tweak the contrast so that the sky is darker and the light points stand out? Its sensitivity is such that it could be great for this purpose, and I think a lot of people would be interested - IF this were possible. 

I've tried to attach an example showing very clearly how it is / how I'd like it to be, but the image uploader on this forum does not work (bizarrely it says "Image source URL is missing" which makes no sense). Hopefully you get the idea. 

Thanks.
