NGC 2070 in Doradus

Hi all,

Work in progress on 52 hours of data on NGC 2070 and surrounds.

What a spectacular region of the sky.

I'm not entirely sold on the palette, but, it is so abundant in oxygen III that it overpowers the region in blue/green in the traditional Hubble palette of sulphur II mapped to red, hydrogen alpha mapped to green and oxygen III mapped to blue.

This was captured over 31 nights. I look forward to presenting the final image (when I'm a bit more satisfied).

SBIG STL-11000M, Takahashi FSQ-106N, Losmandy G-11 Gemini
SBIG Remote Guide Head, Takahashi FS-60CB
15.5 hours hydrogen alpha, 17 hours sulphur II, 19.5 hours oxygen III
1800.0s (each sub-exposure per filter) f/5.0 at 530.0mm -25 degrees Celsius

Larger version available here.

Thanks for looking.
