 Go2Alpha
 BLW @NMRC

 This script creates a UI in DigitalMicrograph that helps tilting the stage for setting eucentric height.
 Two angles can be defined, "Alpha 1" and "Alpha 2" in degrees. Pressing the correspinding button will move the
 microscope stage to the defined angle. The "Tilt Neutral" button will set the stage angle to 0.
 Care should be taken by the user that tilting to the defined angle will not cause a stage touch. If in doubt, check the maximum tilt range of your
 stage before using this script.
 Alpha refers to the tilt-x axis in a JEOL microscope. This script does not control the Beta tilt axis in double-tilt holders.
 If you found this script useful, consider citing: http://arxiv.org/abs/2507.10247
