IC434_Bi-Colour_2017-1-17

This was an end of session image and to see what this camera can do with just 3min exposures. The seeing was not good but better than it was earlier.

The Stars are not good and bit of a blue edge round the star Alnitak but I've spent far to long on this already, might try and sort this out later.
