NGC6503

Spiral Galaxy in Draco

Uploaded 6/18/02

Inclined spirals are always exciting to image, you get the details in the yellow cores and the dust lanes that are dominant in edge ons. This bright 10.9 magnitude Sc spiral is quite large at 7 arcmins long. Its tawny core and light blue arms compliment the brown dusty lanes within. The 8.6 magnitude K5 star off to the left bloomed across the entire field in the luminosity frames. A side note to this image is that the small double star near the bottom of the frame directly below the nucleus is listed in the Hubble Guide star Catalog as a non star.
