Multiple sequential exposures

For each single-exposure command, there is a multiple-exposure equivalent that takes a series of similar frames.

For example:

ICL> multrun red 5 30 "Time sequence 1"

starts a series of 5 30-second observations. Each observation is logged with the same title.

Alternatively, you can take a series of exposures and store them in one image-cube. If you define your image format to have more than one plane, the run commands expose each plane in sequence and then save the cube to a single file on disk. This is slightly more efficient than multrun and its relatives, but only one set of FITS headers and one log entry are made, so you lose the record of the exact starting time of each plane.
