Great result, well done!
I assume the spectrograph is in Littrow configuration.
Which processing software are you using??

Ohnishi,
Thanks for that, appreciate.
It would be worth while trialling the INTI processing software. Much faster than SLiM and does the geometric corrects as well as a "prominence" image.
