Description

My first globular cluster for a long time. This is a special one, because it has a planetary nebula inside near the core. Very difficult to find, you have to know exactly where to look at. It's a little bit green from the OIII filter. I made Ha too, but could not really find it there.

On one of the test frames I found a little pixel-worm of cosmic rays hitting the sensor. Some Hubble-Raw files are completely full with this little worms.
