I think  have ironed out a few more niggles with the latest DIY spectrometer (must get around to a write up!). Replacing the 50mm SLR collimating lens with a Paul Rini 0.63 focal reducer has upped the resolution nicely.

 

Here are 3 Be star spectra captured on the 11th Jan. 10 Cas was quite challenging and needed 2x2 binning due to the low SNR.
