Removing the Noise

 So! Noise!

One of the biggest problems I have with my night/astro-photography is noise.
I shoot at around 800 ISO to keep the amount of noise I'm afflicted by to a minimum whilst still maximising the amount of light my camera(A Nikon D90) is picking up.

I won't go into the details really. I'm only using readily available plugins and bits and bobs but I thought I'd post some comparison shots of older photos I have taken where I have always regretted the amount of noise in, next to images with some noise reduction used.

It was difficult to tweak the noise however without tweaking a few other things which is why you may notice some slightly more drastic differences in the images.

In some cases I think the noise reduction I've done  is still not quite enough, I'm not sure.

If you know any anti-noise techniques and would like to share them please do. Either leave a comment below or feel free to contact me. I'd be very interested.
