Comet 45P Honda-Mrkos-Pajdusakova (2)

The next chance to catch the comet occurred on 2nd of January. Despite a weather forecast, the sky was clear.

During the session, the comet was very close to the horizon (~8 degrees).

I used Canon EOS 600D + EF 50mm f/1.8 @f/2.5 on tripod (through open window), ISO=400.

Here is a result of stacking of 77 frames (3.2s each) in Deep Sky Stacker (19 darks and 19 offsets were used for calibration) with subsequent processing in FITStacker and RawTherapee.

A size of the visible field is 4x4 degrees.

The comet is in the center like a green star. A faint star near the comet to the upper-left has a visible magnitude 9.6m.
