The rather large nonvolatile memory allows a lot of software to be stored in the camera itself. The nonvolatile memory can hold 3 pictures in raw form. Selecting windows decreases the number of data, allowing the storage of more pictures. Zooming in of parts of the video matrix. So some electronic zooming is possible.
Image compression can reduce the amount of data and so increase the storage capacity.
JPEG compression is already available. Other methods better suited for astro pictures can be programmed. Possibly wavelength compression is a solution. Setting a crosshair on a guide star on the screen for automatic guiding. This function requires a relay box connected to the camera.
