Comet 2012 F6 Lemmon 15 February 2013

Stack of 12 x 30 second exposures of comet C/2012 F6 taken on 15 February 2013 using iTelescope T12. Images registered on the comet and stacked in ImageJ, coveted to a Median Z project to bring out the detail in the tail. Same as the other image but with a SUMMED Z stack, trying to bring out fainter details. Comet coma is over exposed. Click on any image to embiggen.

I have finally finished processing my images of C/2012 F6 Lemmon from the 15th (only took a week and a half, but 2012 DA14 and an occultation and a bunch of other stuff came up (like my sons 16th birthday party).

I'm not sure I'll get any more of this comet using the iTelescopes, it's pretty close to their limit of travel towards the horizon. This was meant of be part of a mosaic including 47 Tucanae, but the second imaging run crashed (maybe do to the cloud which affected these images). But that doesn't matter, amazing detail.

Animated GIF of the comet (12 images every 30 seconds).
