Quick tip - more instances on OS X

[edd]

I don't think this is as common knowledge as it should be, and it's not obvious how to get a second copy of an application to run on a Mac but it's particularly nice to be able to do so in PixInsight. So... open a terminal and
open -na PixInsight
There you go

Hi. You can also do this from PixInsight. On UNIX and Linux versions of PI, enter this command from the command line (at the bottom of the Process Console window):

!!$PXI_BINDIR/PixInsight

The two leading bangs (!!) run an external program, the PixInsight executable in this case, as an independent process. This is known as a daemon on Linux/UNIX. If you use a single bang, the newly created process runs as a child of the current PI process, which blocks it.

On Windows, this is a bit more complicated (Windows doesn't love command lines):

cd "$PXI_BINDIR"
!!cmd.exe /C PixInsight.exe
