I tried the spectrum tonight...
As suspected, SN is maybe too dim to pop out of background LP.
Maybe I should stack couple of tens of frames to improve S/N ratio and stretch the histogram a bit.
Also, without FR the background glow will be 3x lower.. possibly enough for spectrum to dominate.
This is crop from single frame, 2 minutes @ISO1600 (C11+FR+SA100+Canon 450D(modded)).
