Second image is a 20 second image through a red filter started at 00:42:00 has been processed using a rotational gradient filter with rotation 10 degrees and amplification 10.

Third image is a 20 second exposure of Hale Bopp, taken through a blue filter was started at 00:24:51 UT has been processed using a rotational gradient filter, with rotation 10 degrees, and amplification 10. Note the spiral structure that all of the professional observatories have been reporting recently.... cool!
