Astrophotography – the difference a color cooled camera makes

Tonight I’m shooting images of NGC4038, and NGC4039, two interacting galaxies. Here is an example taken with a ZWO-1600 cooled camera with the cooling off and on. 

Both images are 300 second exposures consecutively taken, with the one on the left when the camera was at 11.7 deg C, and the one on the right, cooled to -16 deg C. Proof that cooling makes a huge difference.
