Quote:IC 434, Barnard 33 - Horsehead Nebula. Nov 15, 2012The Horsehead Nebula is a dark nebula in the constellation Orion. It is approximately 1500 light years from Earth. The red or pinkish glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Horsehead is a stellar nursery; bright spots in the Horsehead Nebula's base are young stars just in the process of forming. The darkness of the massive nebula is not explained by the dust and gas, but by the complex blocking the light of stars behind it. The heavy concentrations of dust in the Horsehead Nebula region and neighboring Orion Nebula are localized, resulting in alternating sections of nearly complete opacity and transparency.[Wikipedia]•3x5min (ISO 1600)•2x8min (ISO 1600)•5x10min (ISO 1600)•1x12min (ISO 1600)•93min integration, guided•Canon 60Da/IDAS LPS-P2/254mm TMB APO/elCapitanProcessing Workflow: (Updated instructions here...)•RAW file conversion in ImagesPlus 5.0 •Align TSR/Combine/Crop in ImagesPlus 5.0 •Digital Development in ImagesPlus 5.0 •Multi Point Planar Flatten Background in ImagesPlus 5.0 •Multiresolution Smooth-Sharpen + Inverse Luminance Mask in ImagesPlus 5.0 •Geometric Transform/Scale in ImagesPlus 5.0 •Adaptive Richardson-Lucy Restoration + Luminance Mask in ImagesPlus 5.0 •Smoothing in ImagesPlus 5.0 •Contrast, 'Noise Reduction', and Sharpen in Photoshop Extended CS6 •Star Size and Halo Reduction in ImagesPlus 5.0•High Pass Contrast Enhancement in ImagesPlus 5.0 [without Star Mask]•Curves, Contrast/Brightness, Saturation, and 'Noise Reduction' in Photoshop Extended CS6Combined/Unprocessed FIT here...•Full frameLarger file...

Quote:That's a cracker of an image!I find one thing puzzling/intriguing though in your (really good and thorough) processing document. You seem to perform deconvolution on data that is already stretched globally, modified locally, as well as smoothed.Mathematically applying deconvolution at that point does not make a whole lot of sense, as the point spread function that needs to be recovered will now be varying all over the place. Wouldn't you get much better (and mathematically correct) results by applying deconvolution prior to stretching as soon as you load the data?
Quote:The contrast and details around "The Head" are remarkable. Excellent job on the processing and thanks for posting. That's a wall hanger for sure...
