|Siding Spring on 18 October, the comet has come over the dust clouds, so is easier to see. Mars if now in view at the bottom of the image grossly overexposed. Stack of 2 x 30 second luminance images taken with iTelescope T12, SUMMED in Image J. Definitely click on the image to embiggen.

Tomorrow comet C/2013 A1 Siding Spring
comes closest to Mars
. Watched by a flotilla of spacecraft from Mars, and a batallion of amateur and professional observers.
Hopefully the weather will hold. Friday night was clear but I missed observations as I was picking up EldestOne during optimum observing time. Tonight was cloudy, but the robot scopes at iTelescope
picked up the comet for me.
Unfortunately, my kids have used up all the high speed bandwidth, so despite having heaps of pictures, downloading them takes forever. You can see my images of the comet near the butterfly cluster here
Here's hoping tomorrow night is clearer.
