M17 Omega Nebula

[Barry]

From a few nights ago. I finished up at around 3am but fell asleep on the floor next to the telescope. Woke up at 6 with ice dripping onto my cheek from the dome above.

3 hours 20 minutes of exposure on the Omega Nebula.

The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter.

No cropping. Prime focus of the GSO RC12. Nearly two and a half metres of FL.
