Great image Jeff. Keep on layering

I also captured a swag of frames at shorter exposures (1min & 30sec), but did not ending up using them when layering. I could not work out why people bother with shorter exposures when layering, rather than just processing copies of the long exposure data stack for dim, medium and bright image regions. Would appreciate if someone could help me out here.http://www.iceinspace.com.au/forum/..../shrugging.gif

How did you do the processing? Did you stack the 4x3min exposures and then used the same exposures (darkened) for the core when doing layers? Or did you use some other way?
I can imagine that, depending on the exposure time, the long exposures can have the bright parts overexposed and darkening them won't bring out the details which could be obtained if a shorter exposure was used.
