Weather cleared last night. I had to use Rigel as the reference star when (again) 52 Ori yielded images of the wrong size (all other were fine, a mystery). This permitted me to go through the entire process except telluric lines. Some profiles are attached, including my first nebula (low SNR). I am still trying to learn more about response curves, next step is to figure out telluric lines.
Critical comments most welcome,
Ed
