Description

Taken in the East of Sierra Nevada Mountains.

Camera: Pentax K-1

Lens: Rokinon 135mm F2 @ f5.6

Mount: Celestron AVX

ISO: 3200

Exposure: 60 seconds

8 frames manually stacked using median mode Photoshop CS6.

Color gradient filers were used to minimize the orange color near the horizon.

This is a smaller version of the original file which is about 20 Mega Pixels.

I would have liked to have taken more frames. The problem with too many frames is that the comet was positioned near the horizon and too many frames result in distortion of the relative position of the stars as the comet sets between frames due to atmospheric lensing. This makes stacking difficult. At least for my limited skill set.



I'll try to do a better job the next time it comes around in 6,800 years.
