Apart from the laptop shutting down, a satellite passing through the frame and you tripping over a sand pit, sounds like you had a fun night Leon.
This story pretty much sums up the life of an Astrophotographer. It takes 10 bad nights where everything goes wrong, to have one good night of imaging.
The image has come out very nicely. Nice detail in the Helix and the widefield view is lovely.
Well done.
