NGC 7023 - The Iris Nebula
An area of reflection nebulosity illuminated by a very youthful (<5000 yr old) Herbig Be star (HD 200775).

  • RA: 21:00
  • Dec: 68:10
  • Size: ~18'
  • Magnitude: 7.1
  • Distance: ---
  • Constellation: Cepheus
  • Millennium Star Atlas: Vol. III, p. 1061-2
  • Scope: 12.5" Ritchey-Chretien at f/9
  • Autoguider: ST-4 in average mode
  • Sky conditions: Moderate transparency, superb seeing
  • Film: FLI Dream Machine CCD
  • Exposure: 27x90 seconds L, 10,8,9x360 seconds RGB
  • Date: 7-29-03 L and 8-23-03 RGB

The same situation existed here as for the NGC 5907 shot. NGC 7023 did not come into position until such time as it was not possible to shoot a full RGB color set. So, I decided to hammer out a few more luminance frames instead. Come August, conditions permitted the addition of the color data.
