Err, what?!  4043 bytes of C, for an IBM PC Emulator?!  This is pretty incredible for the International Obfuscated C Code Contest.

Getting the code down to <= 4096 characters to meet the IOCCC rule 2 overall size limit required a good deal of effort (and appreciable risk of divorce), with obfuscation being a pretty unavoidable consequence in most places … for the rest, I use short circuit operators whenever possible, mix x[y] and y[x], don’t use any flow control keywords except for for, use K&R-style declarations to honor the C language’s rich cultural heritage (plus it saves a byte), and occasionally go overboard with nasty nested indexes to give things like this: –64[T=1[O=32[L=(X=*Y&7)&1,o=X/2&1,l]=0,t=(c=y)&7,a=c/8&7,Y]>>6,g=~-T?y:(n)y,d=BX=y,l]

No clouds tonight!   Seeing is a little soft, but at least the sky isn't opaque.   Here's NGC 5985 (far right, face-on spiral galaxy), NGC 5982, NGC 5981 (left edge-on spiral).  This is a stack of 5 frames, 10 minutes each, unfiltered luminance.  There's a few more galaxies in here too; can you find them?   QSI 583wsg camera, A-P 305RHA.

Out in the observatory tonight; clear skies, no moon.  Happiness is a night with good seeing and an autoguider tuned right in.  Scale is roughly arc-seconds of error.   RIght now, taking 600 second long R,G,B series of images.
