On this UVEX is fixed :
- The ALPY 600 auto guiding module
- The ALPY 600 calibration module
- A CMOS sensor for science image (ASI 183 MM Pro)
- A CMOS sensor for auto guiding (ASI 174 mini)
With this UVEX, it's very easy to change the grating without opening the spectrograph. You have just to unscrew a large button and change the grating support.
