The shorter exposures were to capture Orion's bright core and surrounds. At 5 min the core was blown out, i.e. just white and no detail. Once the images were stacked in DSS, I processed it in Photoshop.
I wasn't sure how DSS would handle the different exposures and if it would lose the detail in the core if I stacked them all together, so I tried it to find out. The last time I imaged Orion I stacked the different exposures separately and then combined them in PS using masks. This time I added all the images at once and it seemed to work. Some selective use of curves and masks bought back the core.
