Experimental image processing to bring out the comets tail in more detail :

This image is a combination of three different exposures : 20 x 10 s, 20 x 20 s, 15 x 30 s.
Comet mode stacking in Fitsworks on each set. Then combine, star reduction, spectrum adjustments etc. Final tweeking and B/W processing done in PS6.

During image capture, I got dew on my old ETX OTA (piggyback mounted on the LS 8"), and I tried to
counteract this by adjusting the focus at the 20s and 30s exposure series.
The result is a little bit out of serendipity.
