For those who dare - please try the new version of Pixinsight1.59
http://pixinsight.com/forum/index.php?topic=1496 .
I have grown to like pixinsight a lot - so much so that the features it has far outshines the other software i have used. I use Deepsky stacker to do the stacking at the moment, but everything else is within Pixinsight. Eddie T uses it so it cant be bad

. don't get me wrong - i own Astroart 4, Images plus 3.80.
it is the only application i know that is standard for 32 and 64 bit machines for windows, Mac and Linux
try it - there is a demo version available
