The Trifid Nebula in Sagittarius. This image is a stack of 8 eight minute exposures shot through a Hydrogen-alpha filter. The exposures were acquired using an SXV-H9 CCD camera on a Vixen R200SS 8" f/4 Newtonian equipped with a Paracorr. The exposures were calibrated, defect-corrected and stacked using AIP4WIN. A few new experimental tools were applied to enhance the structure. This image has been resampled down from its original size of 1392x1040.
