PHOTO OF THE MONTH<\/span><\/strong><\/h6>\n\n

Pickering\u2019s Triangle mosaic<\/strong><\/h4>\n\n

Paul Ecclestone-Brown, Lichfield, 28\u201329 August 2021<\/strong><\/p>\n\n

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

Paul says:<\/strong> \u201cThe Midlands was under almost permanent cloud cover all summer. As I ran out of data to process normally, I decided to experiment. I\u2019ve been fascinated by symmetry and Newton\u2019s colour wheel, so I combined the two concepts in a single image.<\/span> I took an over-stretched, starless image of the Cygnus Loop and clipped a triangular portion of Pickering\u2019s Triangle from it. I pasted that into Photoshop several times, rotating and reflecting while shifting the hue of each triangle.\u201d<\/span><\/p>\n\n

Equipment:<\/strong> ZWO ASI294mm Pro camera, William Optics RedCat 51 refractor, iOptron CEM40 mount <\/span> <\/p>\n\n

Exposure:<\/strong> Ha 15x 300\u201d, OIII 18x 300\u201d <\/span> <\/p>\n\n

Software:<\/strong> NINA, PixInsight, Photoshop<\/span><\/p>\n\n

Paul\u2019s top tip:<\/strong> \u201cGet confident with dedicated astro-image processors and more general packages like Affinity Photo, GIMP or Photoshop, especially in colour manipulation, layerclipping, rotation and reflection.\u201d<\/span><\/p>\n\n

Saturn and its moons <\/strong><\/h4>\n\n

Dan Fleetwood, Rugby, 16 September 2021<\/strong><\/p>\n\n

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

Dan says:<\/strong> \u201cI\u2019ve always struggled to capture a crisp image of Saturn, so I was pretty pleased when I realised I\u2019d also captured Dione, Tethys, Rhea and Titan.\u201d<\/span><\/p>\n\n

Equipment: <\/strong>ZWO ASI290MM camera, Celestron NexStar 8SE <\/span> <\/p>\n\n

Chris Duffy, Wark, Northumberland, 21 September 2021<\/span><\/strong><\/p>\n\n

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

Chris says:<\/strong> \u201cMy equipment is suited to deep-sky imaging, but the Moon was so bright and close to the exact time of being full, I took the opportunity to take a single three-minute video.\u201d<\/p>\n\n

Equipment: <\/strong>ZWO ASI183MM camera, Sky-Watcher Equinox 80ED refractor, Sky-Watcher EQ8 mount <\/span> <\/p>\n\n

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

Bill says: <\/strong>\u201cBecause it\u2019s near other enticing targets like the Crescent Nebula, this small emission nebula is often overlooked by imagers.\u201d<\/span><\/p>\n\n

Equipment:<\/strong> ZWO ASI1600MM Pro camera, William Optics FLT98 refractor, Celestron Advanced AVX mount <\/span> <\/p>\n\n

Lee Pullen, Bristol, May\u2013June 2021 <\/strong><\/p>\n\n

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

Lee says:<\/strong> \u201cI like challenging the conventional wisdom that OSC cameras aren\u2019t suitable for use under light-polluted skies. This was taken from Bristol city centre using an L-eXtreme filter.\u201d<\/p>\n\n

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

Douglas says: <\/strong>\u201cI started capturing this nebula back in January 2018, but finally got round to reprocessing it in the HOO data palette.\u201d<\/span><\/p>\n\n

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

Drew says: <\/strong>\u201cI\u2019ve been striving to capture this object for years. It took some really dark skies, three nights and nearly 18 hours of data.\u201d<\/span><\/p>\n\n

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

Ed says: <\/strong>\u201cThis two-panel mosaic is the first image taken from our new home in Suffolk. We were still unpacking, but I couldn\u2019t miss the opportunity of our new darker Bortle 3 skies.\u201d<\/span><\/p>\n\n
