1. A system comprising:
a sensor subsystem comprising one or more sensors configured to sense electromagnetic radiation; and
an optical subsystem defining a plurality of optical paths comprising at least a first optical path and a second optical path, each optical path being within the system, wherein each optical path is configured to carry electromagnetic radiation from an object space to the sensor subsystem, wherein:
the optical subsystem comprises a telescope, and the first optical path passes through the telescope;
the second optical path does not pass through the telescope;
the first and second optical paths merge at a merging point between the telescope and the sensor subsystem, and the first and second optical paths are disjoint upstream of the merging point, wherein a first input collecting aperture at a first location is in the first optical path and a second input collecting aperture at a second location is in the second optical path, wherein the first and second optical paths do not meet between the first or second input collecting apertures and the merging point;
a magnification provided by the second optical path at the merging point is different from a magnification provided by the first optical path at the merging point.
