Comet Jacques  C/2014 E2
in the evening sky
August 29th, 2014

 Here is last nights shooting of the comet, still in a very rich part of Cepheus. Now beaming at magnitude 7, the comet has a very faint gas tail, and a broad short dust tail.

Three processing methods are shown here, all with the same 60 minutes of data using 2 minute sub frames. The first is stacking the comet and the stars in one hour show the movement of the comet during that interval. A very rich star field indeed!

The second method is to combine the median stacked image with the star stacked image, after subtracting out the trailed comet. It is a realistic portrait of where the comet was on the first shot in the sequence.

The final third shot is a median combined image, showing the very faint tails at the expense of the stars.
