This is from old data pre fridge so it is noisy. The new version of Easyhdr was used to obtain the tone mapped image.

Details Canon 5DH, Canon 300mm F2.8L at f/2.8, hutech LPR filter.

Exposures 10x(1m at 200ISO, 1&2min at 400ISO, 2&4min at 800ISO)

Last year we had cloud in Melbourne while this region was potentially visible. This year will try again with the fridge.

A nice image Bert, it is a good guide for visual observers too. I find IC4603 in the center of your image the easiest to see with a scope.

Hi Bert
Yes the fridge will do wonders with this area filled with such faint nebulosity. The wide dynamic range especially near Antares is impressive there.
