Helix Nebula

heleixoct25crp

19 hours of exposure of this beautiful nebula. From my location the nebula never gets higher than about 35 degrees in the southern sky, so it is challenging to get the detail I'd like to see. 

This object is one of the closest to the Earth of all the bright planetary nebulae. The estimated distance is about 215 parsecs or 700 light-years.

The image was taken over several nights ending on October 25, 2013. Most of the imaging time was spent on getting the red glow through a hydrogen alpha filter. Imaged with my Hyperion 12.5" astrograph and the session was under the control of CCDAutopilot software. Click on the image for a larger view.
