If noise is your issue, try DXO Optics. Best noise reduction software out there.So.. question ... do you get better sharper images using longer exposures?
Still trying to work out why my images are noisy and soft when I take one at night. I messed about with a technique today that involved a median stacking method in photoshop to remove noise. Do you do anything like that ? Or are you getting this good an image from a single frame?
It is driving me insane. My night time shots are shocking...
What exactly are you trying to shoot at night?
