The Helix Nebula, also known as NGC 7293, is a large planetary nebula located in the constellation Aquarius. This object is one of the closest to the Earth of all the bright planetary nebulae. The estimated distance is about 700 light years and spanning 2.5 light years.
The Helix Nebula is formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. The remnant central stellar core, known as a planetary nebula nucleus, is destined to become a white dwarf star. Currently, the age is estimated to be 10,600 years.

Looks like a good start Ben for 100 mins of data.
You can see the resident galaxy OK, (just underneath the bright orange star).

As you know some folks here are doing marathon runs at the Helix in Ha. It would be interesting to see a OSC image done at 50+ hours.
