Comet ISON – New Tail Feature?
by Mike Hankey, under Comets & Meteors
I noticed a new prominent feature in the tail of Comet ISON while imaging it this morning. It looks like a thin jet towards the top.
Below is a comparison of today’s image with the last one I took just two days ago on November 8th. You can see the trail is just barely visible on the 8th.
Here is an inverted version of the same picture. Its a little easier to see the features in the inverted picture.
Here’s the color version of just the comet this morning.
And here is the color stacked with trailing stars. (I will come back another morning to image the star field and complete the final picture).
These images are the result of 5×3 minute exposures of Red, Green, Blue and Luminance at 3×3 binning on the morning of November 10th, 2013.
If you have noticed this feature already, please email me links to your most recent images. I’d love to compare.
