Description

Gary Imm has done the only other image on Astrobin here.

Gary's description of the most prominent of the Kohoutek objects is worth a gander... much more work than I will every be able to accomplish.

I also put up an early H-alpha version (D).  The O-III really overwhelms the H-alpha despite the fact that it also is very strong.  I checked the color with Alex's NarrowBand Assistant and that is what is seen here (Blue mostly), cleaned up with StarX etc. and GHS. 

Finally I put up and attempt (E) to equate the O-III and H-alpha signals in PixelMath, which is not a big success.
