Comet C/2013 A1 (Siding Spring) and the Butterfly Nebula (M6) on October 7, 8, 9 2014


7 October 2014, Comet C/2013 A1 (Siding Spring) approaching the Butterfly Cluster (M6), stack of 10x 30 second luminance images (summed in ImageJ) with iTelescope (Q62) T12 0.1m f/5.0 Astrograph SBIG STL-11000M, North top. Image cropped to 800x600 from original. Click to embiggen	8 October 2014, 9 x 30 second luminance images. Other details as for the 7th.	9 October 2014, 3 x 30 second luminance images. Other details as for the 7th. Cloud seriously messed up the exposures :-(

I now have a set of images for C/2013 A1 (Siding Spring) approaching the Butterfly cluster (M6) from the 7th to the 9th. They are not ideal, due to a combination of Moonlight, cloud and Moonlight AND cloud. iTelescope T12

Wide field of C/2013 A1 on Tuesday 7th. Click to embiggen, it is very big, but you will need to in order to see the comet (stack of 10x30 sec images, I took 20, but stacking more smears the comet nucleus, compare with the full field image from the 8th.
