The Cat's Paw Nebula (NGC 6334)
NGC 6334 (also known as the Cat's Paw Nebula, Bear Claw Nebula and Gum 64) is an emission nebula and star-forming region 5,500 light-yeas away in the constellation Scorpius. It was discovered by astronomer John Herschel in 1837, who observed it from the Cape of Good Hope in South Africa.
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm.
About this image:
2 minute ISO 3200 exposures, imaged in the rural dark skies of the Waterberg, Limpopo Province, South Africa.
Star Colors:
You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.
Gear:
GSO 6" f/4 Imaging Newtonian Reflector Telescope.
Baader Mark-III MPCC Coma Corrector.
Astronomik CLS Light Pollution Filter.
Orion StarShoot Autoguider.
Celestron AVX Mount.
QHYCCD PoleMaster.
Celestron StarSense.
Canon 60Da DSLR.
Tech:
Guiding in Open PHD 2.6.1.
Image acquisition in Sequence Generator Pro.
Lights/Subs: 15 x 120 sec. ISO 3200 CFA FIT Files.
Calibration Frames:
30 x Bias
30 x Darks
Pre-Processing and Linear workflow in PixInsight, and finished in Photoshop.
Astrometry Info:
nova.astrometry.net/user_images/1156498#annotated
RA, Dec center: 259.794674057, -35.8560064566 degrees
Orientation: 0.919617580021 deg E of N
Pixel scale: 5.29428727941 arcsec/pixel
