This is 2h15m (15x3m GPrime, 15x3m RPrime, 15x3m IPrime) taken with the Plaskett telescope on October 26th. It is a false colour result (GPrime mapped to blue, RPrime to green, and IPrime to red).
As a result, there are some really interesting hydrogen knots in the arms that would typically be red, but appear green in this image.
