Fig. 8.
Sample image illustrating frame transfer smear trails, which are enhanced for very bright targets. In this example, the V-band magnitude of the target is 4.5, and the image is a stack of 39 exposures, each with duration 0.1s. The circular cut out to the 200 × 200 pixel sub-array is applied in order to maximise science data down-link.
