Last night's low-res spectrum attached (16.58 Dec 2013 UT), SA100 grating with Canon 650D & 200mm lens on Vixen Polarie, 18 x 13 sec, ISO 6400, F/5.6. Nova at 9-deg altitude, bright moonlight, imaged from White Cliffs, NSW, Australia (30.8-deg S). The black area on the left of the bar was an overlapping 'spectrum' of a tree in moonlight!
Cheers -
