I think a 0.6sec exposure is way too short, unless you have a very large scope and a very bright target. I assumed you were using a C8+DSLR, is this correct and if so, is the DSLR a CMOS sensor? I'm using a C8 with a monochrome, binned, CCD and still need to stack 5 x20sec exposures to get a reasonable SNR.
