Trevor,
Cheers. Cotton thread. It was something Mike Sidonio recommended about 3 or so years ago but never got to try until Friday.

David,
Thank you, sir. Yeah, I'm almost tempted to sell the 40D now, hah!

Stuart,
Bite it, bite it!
Why the long exposure? Why not? Us paupers with DSLRs need to take lots of exposures to flatten out the noise in the sky background. There is an immense difference, in my experience, between taking a handful of exposures, and a crapload of them. It was also a test of the camera to see how it would handle at ISO-800. I am pleased to say that in the high resolution original file, there is virtually no perceptible noise in the background. Taking dark frames immediately after the imaging session may have something to do with that. Also, it was just above 0 degrees out there that night. That would play a big part, too.

Why such a long exposure on a star cluster?
I could understand if you wanted to get some nebulosity that is surrounding the area, but I didn't see any.

Cheers, boys.
