Thanks, Peter, I see that your stacked image of Antares is very similar to what I am seeing in mine. I think I will need to improve my processing skills until I am happy with it, which will probably be never haha!

Ryan, I wasn't getting these squiggly iris lines with my Canon 60d attached to the same refractor, and last night I removed the filter and took a few snaps and still had the same result. With the filter now ruled out, it leaves the combination of 72ED optics, ASI183MC-Pro, and 0.85x reducer. Therefore my next experiment will be trying different back-focus spacing between the camera and reducer, it may be just out either side of the optimal distance.
