Stacking Stars for Less Noise

Stacking Stars for Less Noise

NIKON Z 7 + 14.0 mm f/2.8 @ 14 mm, 15 sec at f/2.8, ISO 3200 x 7 Frames

Here is a very close up shot of a small portion of yesterdays image of the milky way. These crops represent significantly less than 1% of the overall original frame

The top part is from the single 15 second exposure at ISO 3200. No colour noise reduction has been applied. You can see there’s a fair bit of noise in the image (especially when viewed here at 100%)

The lower part is the result of stacking the seven (7) shots I took. Each of those frames was the same 15 seconds at ISO 3200. When aligned and averaged in software it noticeably reduces noise. However it still retains the sharp pinpoint stars
