M42 Stacked !!
After much gnashing of teeth, tearing of hair and general pandemonium I finally found a process that works. I converted the frames to TIF and went back to DSS 3.2.2 to stack them. So 58 frames in exposure groups of 5, 10, 15 & 20 secs totalling 17 minutes all at ISO 800 with the SONY A77 and the Lunt. No filter and there is some serious vignetting due to the optical train setup I had at the time. But I'm happy to get something decent out of it and even the Running Man Neb can be seen.
I still haven't figured out why DSS 3.3.3 beta is not working for me.
