Kevin that's an awesome shot mate. I see your getting your new toy in order. Collimation can be tricky with the F4's as you said. It took me a while to get mine like it is, and I'm still not sure it is exact. The most important thing I found with the f4 as apposed to my f5 that I have, was the placement of the secondary mirror. Took me ages to get the secondary in just the right spot so that the primary is not truncated after making the collimation adjustments. I also had some focuser tilt that a while to sort out. Your doing really well to get such detail with just 12 minutes mate, so your's can't be too far out. Great job.
