Butterfly Nebula

NASA, Astronomy Picture Of The Day, part I
http://apod.nasa.gov/apod/ap081107.html


Wind made imaging really difficult. About half of the frames was shot trough speeding clouds.
In this image colors are showing difference between Double ionized Sulfur (Red),
Hydrogen alpha (Green)
and triple ionized Oxygen (Blue).
This palette is generally known as a Hubble palette by the palette used to processing images from Space telescope Hubble.

Imaging data: -
Camera,
QHY8 -
Optics,
Tokina AT-X 300mm @ f2.8

- Exposures,
5 X 1200s H-alpha 3 X 1200s O-III
4 X 1200s S-II + flats and bias
- Guiding, LX200 GPS 12" + PHD-guiding and Lodestar
