The Omega Nebula, M17, an emission nebula in Sagittarius.
This image is a hydrogen-alpha color composite of a stack of 8 eight minute hydrgen-alpha filtered luminance exposures
and 4 eight minute exposures for each color channel.
The colors were G2V balanced using AIP4WIN V2.
The exposures were acquired using an SXV-H9 CCD camera on a Tele Vue NP127 5" f/5.2 refractor.
The exposures were calibrated, defect-corrected, stacked and color-combined using AIP4WIN V2.
The Ha luminance channel was Wavelet sharpened using AIP4Win V2.
This image has been resampled down from its original size of 1392x1040.
