 I’ve recently been working on the interactions between the camera and focus to capture tiles and enabling autofocusing. I thought I should detail some of the aspects of this part of the project while they are fresh in my mind.
 
 Because we are using an `open loop system 
-<https://en.wikipedia.org/wiki/Motor_control#Open_loop_control>`_ the microscope doesn’t have a way to tell it's current location (only how far it's moved from the starting position). To ensure reproducibility we always initialise the microscope with the focus at maximum height, that way the microscope knows one of its limits, and we can work down from this position.

-When taking photos through the microscope with a camera like the RPi V2, the wide lens results in a lot of black surrounding the actual image we want to capture. Ideally, for image stitching, we'd like a square picture with no boarded. We could manually crop this additional border. However, we have `Python
