Re: [APML] IC1396 in Ha /Tech Pan

Scott, great shot.  The only way to tell if you need more exposure is to try
it.  At f2.8 you may want to test 60 and 70 minutes.  Looking at this shot,
it can be curved a bit more.  I did a curve of in 116 and out 151 without
burning out any of the nebula.  There seems to be a lot of data there.

Great work.

Jim
