For the camera based focus locks:
(1) Convolve camera image with a Gaussian to reduce noise?
(2) Fit area needs to be able to move a few pixels do deal with fitting saturated peaks.
(3) Provide derivatives to the scipy fitting function so that fitting is faster and/or write a little C library to do the fitting.
