That's a great field Robert. I have imaged the 4216-trio, but there are even
more interesting galaxies in the field.

looks nice Robert

your system is really dialed in and working to produce nice data

I think that you can use some selective masking and feathering in Photoshop
to let you not blow out the core of the bright galaxy when you stretch to
reveal the cores of the dimmer ones

try the lasso and then feather maybe 20-50 pixels to mask out the bright
ones when you stretch the others
