I've been interested in this target after taking about an hours worth of data back at the QLD Astrofest a few years ago with my ED127.
Decided to bite the bullet and spend some money renting T27 from iTelescope.
Not particularly happy with the quality of the data - the iTelescope ROR observatory is right near another observatory, and there is a rather bright light on the side of it (that can be seen in the fisheye camera) that leaves a warm blob on one of the corners, among other things.
But here we go.
3hr 50min of data, 10min exposures. Would love more - but it's expensive to rent the scope.
This is a CDK700 27" scope at f/6.6

The light source to the top left, and whatever the source is on the top are rather disappointing for a supposed dark site.
Processing needs work, of course.
