Description

The challenge in processing this data was to balance the brightness of the Rosette nebula with the relatively dim Christmas Tree Nebula. Here MaskedStretch in PI came to the rescue as well as creating different types of masks using StarXterminator which is worth every penny in my opinion.

What can certainly be said of the final image is that it is more compelling than my effort at the same composition early part of last year.

The CMOS optimised Baader f2 filters (Ha and Oiii used here) seem to be working well, although others are less than impressed.
