Description

Continuing my current trend I have again added a long focal length ha/luminece to old RGB data.

The colour data was shot at 400mm as apposed to 1625mm of the ha and was a little difficult to register, however Pixinsight has worked well.

As always any C&C are appreciated. Cheers - George
