The Soul Nebula(IC 1848) is a single 10 min. exposure at ISO 800 and The Cave Nebula(Caldwell 9) is a stack of 3 pics at ISO 800-a total of approximately 28 min.
Canon 10D full spectrum modified dslr on a 6" Astrotech imager with coma corrector and Celestron AVX mount. Auto-guided with SSAG and PHD freeware.
The third pic shows what a plane can do to a long exposure! Looks more like 2 planes.
