Hi Everyone,
Thanks so much for your kind words, much appreciated

It's very nice to get some positive results and encouraging feedback after trying for so long to get a result.
I'll see if my rig can hold up with longer subs, but as I'm shooting from suburban Melbourne, I might have more success with that under dark skies - but I'll give it a try at 10 mins.
Garbz, the image was slightly cropped on the left hand side. Agree a flattener is required, any recommendations? Unfortunately I can't use HLVG as its written for PC only and I'm a mac guy.
Warmly
Andy
