Andy,
Thanks for posting your spectral profile of Chi Cyg. RSpec and an SA200 recent purchases for me, still experimenting with set-up and working through the tutorials, but couldn’t resist having a look after Gary’s first post. Confidence booster to see similarities in the profiles even though mine just a single 20 sec. image with C6/collimator/SA200/DSLR wavelength calibrated only. Thanks.
