Strange Quarks

I took some more images of the comet on December 28, this time from my suburban backyard in Klemzig, again with a Canon 1100D piggybacked on my Meade LX-90.

Both images shown below were stacked and saturation-reduced with IRIS, and cropped with The GIMP. They are quite noisy since no bias or dark frame subtraction was carried out, nor were any flat frames applied; I still don’t have a light box. Effects due to vignetting and dust donuts were obvious on the processed image, likewise for hot pixels, but less so in the cropped portion.

I intend to take some more images when the lunar phase is more favourable in a week or so.
