"BEAUTY NEAR THE BELT" - Sky & Telescope (April, 2018)
At the request of Sky & Telescope Terry reprocessed his earlier color image as a monotone image. This new rendition combines color data (converted to Grayscale) with H-Alpha data to produce a very dramatic effect. Alnitak (below center), the easternmost star in Orion’s Belt, anchors a rich region of nebulosity that features the broad glow of IC 434, with the Horsehead Nebula (Barnard 33) silhouetted against it, and the Flame Nebula (NGC 2024) at bottom center. North is toward left.
Image can be found in Sky and Telescope April 2018 pages 72 and 73.
