Vega was recentered (-0.01 on RA) and the telescope was manually synced. During this test, movements as small as 0.003º on RA proved to have no effect whatsoever. The next step was to test the focuser and the camera. First, while still on continuous mode of the camera, the Python-Focuser connection was tested. Python can read the position and move the focuser. Units are steps. 1 step = 20µm | |||||||||
