ngc7380, the Wizard nebula

I rarely do false colour composites, so this approach was a bit ... um ... creative.

 

It's mostly mapped to R:G:B using Ha:(S2/O3):O3 ... but I also added a S2:Ha:O3 layer (blended in), and some tone mapping as well (see J.P.M.'s awesome technique) in order to boost the weak S2 and O3 signal.

 

The stars are pretty bland ... I plan to capture them in RGB and overlay here.

 

Details:

 

Telescope = Takahashi FSQ 85 EDX with .73 reducer (f/3.9)

Camera = QSI 583 wsg

Mount = SkyWatcher EQ6 Pro

Software = capture and stacking in MaximDL, processing in PS CS5

Exposure (Ha:S2:O3, minutes) = 100:180:180

Dates = August/September 2012
