Hi Ivan,

Thanks,

I think part of it is also that this is such a bright object.

I have a stack of the Veil that I hope to post next, but I might have to 
wait until Mike Unsold posts the next beta version of Images Plus to use 
the automatic dark frame matching because my darks are at a different temp 
than the lights.
