Claim One:
1. An imaging system comprising: a primary imaging sensor configured to detect electromagnetic radiation in a first spectral band and to produce first image data comprising a plurality of image frames captured over a period of time; a primary telescope optically coupled to the primary imaging sensor and configured to direct the electromagnetic radiation in the first spectral band to the primary imaging sensor; a secondary imaging sensor configured to detect electromagnetic radiation in a second spectral band, different from the first spectral band, and to produce second image data time-synchronized with the first image data; a secondary telescope optically coupled to the secondary imaging sensor and configured to direct the electromagnetic radiation in the second spectral band to the secondary imaging sensor, an optical axis of the secondary telescope being offset with respect to an optical axis of the primary telescope; a computation module coupled to the secondary imaging sensor and configured to analyze the second image data, produce alignment data, correct the alignment data to compensate for the offset, and provide corrected alignment data; and an alignment module coupled to the primary imaging sensor and to the computation module, and configured to receive the corrected alignment data from the computation module and the first image data from the primary imaging sensor, to align the plurality of image frames based on the corrected alignment data to produce an aligned plurality of image frames, and sum the aligned plurality of image frames to produce an aligned image stack.
