NGC6820, NGC6823 and NGC1514

NGC6820, emission nebula, NGC6823  open star cluster. Lying at a distance of about 6,000
light years in the constellation of Vulpecula is this emission nebula surrounded by an
open star cluster. Notice the pillars of gas that probably contains embryonic stars about
to come to life. Five minute sub frames were captured with matching dark frames using an
Atik 383L CCD camera with a ten inch f/4.8 reflector. The total exposure times were sixty
minutes using a H-alpha filter, thirty minutes using an Olll filter and twenty minutes
using RGB filters:



NGC1514. This planetary nebula is commonly named the Crystal Ball nebula. It lies in the
constellation of Taurus at a distance of about 600 light years. Five minute sub frames and
matching dark frames were captured using a ten inch f/4.8 reflector with an Atik 383L CCD
camera. The total exposure times were five minutes for each colour channel and ten minutes
using an Olll filter:
