Description

The Helix Nebula is a bit low on the southern horizon and provides for a challenging target at 2350mm.  It does require accurate tracking, good focus and long exposures when using higher focal ratios like the Edge HD 9.25". This photo was compiled with Ha and OIII filters at 360 and 600 seconds respectively. Total integration was roughly 12 hours with many subs discarded. At F/10 it was difficult to pull out the subtle Ha features that are at the outer extremities.
