The reduction in noise following stacking of DSLR images of stars is illustrated.(photo: HD 121228, cropped from a single frame (left) and from a stack of 17 frames (right).)
A puzzling (and worrying) feature of dark frames, taken with a Canon EOS 60D, is presented. The author is desperate for a solution!(photo: Figure 1. File size of a sequential series of 40 dark frames taken with a Canon EOS 60D (ISO 1600, 9-s exposure time, CR2 raw format).)
The effect of the number of dark frames subtracted from a light frame on the signal-to-noise ratio (SNR) of stars is investigated. The conclusion is that applying a single dark frame gives a substantial improvement in the SNR of stars, while applying additional dark frames gives only a very small improvement.(photo: Five stars selected for S/R measurement.)
