Get a thin sheet of glass, (I used an old UV filter) put a tiny (and I mean tiny) spec of vaseleine on both sides of the glass, rub it all over the surface with your finger, then run your finger in a single direction over the entire surface, do the same of the other side of the glass but at right angels to the first side (hint, try different angles, gets intersting results too) If you do this correctly, the glass will appear quite clear to the naked eye, just perhaps ever so faintly "foggy", place glass in front of primary, hold it there with elastic bands or use your imagination. It wont interfere with your exposures but it will give you amazing flairing of any and all bright objects such as stars. Wash hands before before touching eyepieces.

Sounds like an interesting experiment Dennis, thanks.
When I worked in TV I was amazed to see how they used to get a soft edge effect on shows (romantic scenes, etc). They rubbed vaseline around the edges of the lens on the TV camera!!!!
Computers do it now, but it horrified me when I saw it done with vaseline.
