Bubble Nebula, NGC 7635, Sharpless 162

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. -



Imaeged in three nights between 27.09 - 04-09 2009, seeing varys between 4-2,5 FWHM -

Telescope, Meade LX200 GPS 12" @ f4.65 Camera, QHY9 Guiding, SXV-AO @ 11Hz

Exposures:

H-alpha 21x1200s Binned 1x1 = 7h

S-II 10x600s Binned 3x3

O-III 5x600s Binned 3x3
