Hi Alun,

That is an interesting setup. I have wondered myself if the guide unit (which can be the tricky part of a DIY spectrograph design) could be incorporated into other spectrograph designs. How did you couple the two together? Did you use the reflective slit from the ALPY?



EDIT: Ah sorry, rereading I see you have two separate spectrographs/telescopes. How are you guiding the DIY higher resolution setup?
