Object V1280 Scorpius, a nova which became visible in early February 2007.  This image was taken near peak visual brightness, but after substantial weakening of the Hydrogen emission lines that had been evident a few days earlier.  The H-alpha line appears to show a hint of the P-Cygni profile that had been present a few days earlier; note the wide absorption especially to the blue side.
Telescope 12" Meade LX200GPS at f/10
Spectrograph / CCD SBIG SGS, SBIG ST-7XME at -30C; Low Resolution = 150 lines/mm
Integration Details 4 x 300s, dark subtracted and sum combined.  More data was obtained but discarded; conditions were very windy that night and as a result some data did not have enough useful signal.
Date / Median Time (UTC) 17-Feb-2007 1220 UTC
Moon Phase 0%
Approximate Airmass 3 (object was low on horizon)
CCD Response Curve Source Alpha Virginis
Wavelength Calibration H and Ne lamps
Software Used CCDSoft, CCDStack, Iris, vSpec, Excel, Adobe Photoshop
Comments The image was taken at the same time using a 105mm apochromatic refractor at f/5.6, with an ST-10XME and an Astrodon LRGB filters.  4x10s Lum, 8x10s Red, 4x10s Green, and 5x10s Blue, cooled to -30C, dark subtracted, flat fielded, mean combined.  As with the spectrum, more data was obtained but high winds made many of the subframes unuseable.  Note that the nova was bright enough to cause saturation of the CCD chip; thus the bright white line extending downward from the star is simply a blooming artifact.
