My original mount for the camera connecting it to the vertical axis lacked adaptability to other cameras other than my own.  This caused problems when the weight of the camera was not perfectly centered along the axis of rotation  which causes skipped steps if doing very small movements or when the camera is completely vertical.  The new mount allows for centering the mass of the camera perfectly along the axis of rotation.  

The new mount has four slots for mounting using the tripod mount on the bottom of the camera as well as the ability to move up and down on the aluminum shaft to find the center of mass. Again all this is hand machined by myself.

on the left is the newly designed mount and the right is the old mount.

As for the rest of the design it remains the same.  With the new camera mount steps as small as 1.8 degrees can be made by the stepper motors which translates to .45 degrees rotation per smallest allowed step at the camera itself.

Everything needed for taking a timelapse excluding camera of course.  All easily fits inside a backpack!
