Tulip Nebula Finalized
Last night I got more H-alpha light and O-III and S-II channels.
-
Two color chemes, HST Palette as S-II=Red, H-a=Green and O-III=Blue. Second image is in natural colors composed from narrowband data. Channels are balanced so, that image match to visible spectrum, H-a + 24%S-II=Red, O-III=Green and O-III + 15%H-alpha=Blue.
-
Processing work flow: Image acquisition, MaxiDL v5.07. Stacked and calibrated in CCDStack. Deconvolution with a CCDSharp, 30 iterations. Levels, curves and color combine in PS CS3.
- Telescope, Meade LX200 GPS 12" @ f4.65 Camera, QHY9
Guiding, SXV-AO @ 11Hz
Exposures: H-alpha 10x1200s Binned 1x1
O-III 6x600s, binned 3x3
S-II 4x600s, binned 3x3

The name "Tulip" is well deserved.

New project, The Tulip Nebula
I have started a new project with a Sh2-101, the Tulip Nebula.
So far, from three nights, I have only four twenty minutes exposures. Weather has been very volatile up here.
I will shoot more H-alpha and other channels for this object later.
