Steve,
IFN stands for Integrated Flux Nebula. You can find out more about it at
http://www.galaxyimages.com/UNP_IFNebula.html
I got a shot of M81 that shows it much better than this shot.

Bernie;
Great shot, lots of detail in a low surface brightness object. I can't image
seeing any of that detail and mottling with any telescope I have ever owned.
What does IFN mean?
