PHOTO OF THE MONTH<\/span><\/h5>\n\n

The Dark Shark Nebula, LDN1235<\/strong><\/h4>\n\n

Catalin Cosar, Henlow, Bedfordshire, 22\u201328 February 2022 <\/span><\/strong><\/p>\n\n

Catalin says: \u201cAlong with the dark Shark Nebula, LDN 1235, two reflection nebulae are visible here, vdB 149 and vdB 150, as well as the distant spiral galaxy PGC 67671, behind the shark\u2019s \u2018fin\u2019. Gathering the data was easy \u2013 the moonless nights helped \u2013 but processing it was a different story. It took a few weeks until I was satisfied with the final image.\u201d<\/span><\/p>\n\n

Equipment: QHY 268C and QHY 268M cameras, Takahashi FSQ-85EDX refractor, Sky-Watcher EQ8 Pro mount <\/span> <\/p>\n\n

Exposure: RGB 165x 180\u201d, L 198x 180\u201d <\/span><\/p>\n\n

Software: StarNet++, PixInsight<\/span><\/p>\n\n

Catalin\u2019s top tips: \u201cFor faint, dusty objects like this, there\u2019s no substitute for dark skies, fast optics and lots of integration time (I had over 18 hours). To bring out the nebulosity without distorting the stars, I processed my two stacks, RGB from my colour camera and luminance from my monochrome, separately.<\/span> Each was stretched and denoised (cleared of unwanted artefacts), then the luminance was deconvoluted (contrast improvement) and the RGB was colour calibrated before combining them. After removing the stars with StarNet++, I stretched them again before adding the RGB stars back in.\u201d<\/p>\n\n

Andy says: \u201cThis is a superb dark-sky spot on the coast. I had to edit out a couple of aircraft trails using the eraser tool.<\/span> If you look closely there\u2019s a meteor near the tower.\u201d<\/p>\n\n

Julian says: \u201cThis was four years in the making. Finally, a clear sky combined with an ISS shadow transit of 0.61-second duration.\u201d<\/span><\/p>\n\n

Adriano says: \u201cI was especially pleased with how this shows off the surrounding reflection portion of the Trifid Nebula.\u201d<\/span><\/p>\n\n

\"\"<\/figure>\n\n

Thomas says: \u201cThe capture of this picture \u2013 of the Milky Way, an ISS pass, the Zodiacal Light and a meteor over the Elan Valley \u2013 involved a 15-minute off-road drive on a bumpy track and a climb up the valley wall in the dark with walking poles and a head torch.\u201d<\/span><\/p>\n\n

Yann Sainty, Vosges and Moselle, France, 3\u201310 March 2022<\/strong><\/p>\n\n

\"\"<\/figure>\n\n

Yann says: \u201cThis is the hardest processing I\u2019ve ever done, due to mixing the Ha (Hydrogen-alpha) in with the LRGB, and separately processing the planetary nebula.\u201d<\/span><\/p>\n\n
