Michael P Caligiuri, Anza Borrego Desert, California, 25\u201326 November 2022 <\/strong><\/p>\n\n Michael says: \u201cSh2-240 is a supernova remnant located 3,000 lightyears away. It\u2019s believed to be the remnant of a star that exploded 40,000 years ago. What sets this image apart from my prior attempts is that I was able to acquire sufficient OIII (oxygen). While dim, there is OIII throughout the filaments, a feature often missed in HaRGB images.\u201d <\/span><\/p>\n\n Equipment: ZWO ASI294 camera, Samyang 135mm f\/1.8 lens at f\/4, Astro-Physics AP1100 equatorial mount<\/span> Michael\u2019s top tips: \u201cShooting with a 135mm camera lens allowed me to capture a full 3\u00b0-span of the sky, and to frame it against a <\/span>starry background. With that original field of view, cropping and framing to taste becomes easy. I\u2019ve been adding RGB data to my narrowband workflow. Once the bi- or tri-colour narrowband layers are blended, I remove the narrowband stars using StarXTerminator and replace them with a more natural-looking RGB star layer. This blend of narrowband nebulosity against RGB stars can be stunning.\u201d<\/span><\/p>\n\n Chris Kotsiopoulos, Reading, 8 December 2022<\/span><\/strong><\/p>\n\n Chris says: <\/span> \u201cIt\u2019s quite an experience seeing Mars disappear behind the Moon and emerge after an hour. I was freezing cold with frost on my equipment, but it was worth it! The processing was a challenge, as I\u2019d never shot an occultation with a CMOS camera.\u201d<\/p>\n\n Equipment: <\/span> ZWO ASI120MM Mini camera, Celestron C90 Maksutov, Sky-Watcher Star Adventurer Pro Shawn Nielson, Kitchener, Ontario, Canada, 14 November 2022<\/span><\/strong><\/p>\n\n Shawn says: <\/span> \u201cI\u2019ve noticed that clusters don\u2019t seem to be imaged as much as more visually striking nebulae. I particularly like this pair of open clusters in Perseus with their pretty coloured stars, as they\u2019re not too tightly packed together and not too far apart. The Double Cluster has just the right appearance. I used LRGB filters in my filter wheel for this image.\u201d<\/p>\n\n Equipment: <\/span> QHY268M camera, Starfield Optics 8-inch Newtonian reflector, Sky-Watcher EQ6 mount Anton Matthews, Bristol, 5 December 2022<\/strong><\/p>\n\n Anton says: <\/span> \u201cRecently I have become fascinated by solar astronomy, and the awe-inspiring chromosphere. I hope to upgrade my setup with a dual mount so I can photograph white light and Ha (hydrogen alpha) simultaneously. I caught this solar prominence ejecting from the disc at about 9:20am.\u201d<\/p>\n\n Equipment: <\/span> ZWO ASI224MC camera, Coronado Personal Solar Telescope, Sky-Watcher Solar Quest mount on Horizon photographic tripod Carl Gough, Littlehampton, West Sussex, October\u2013November 2022, with some data from 2021<\/strong><\/p>\n\n Carl says: <\/span> \u201cI call this the \u2018bubbling rose\u2019 due to the surrounding dust looking similar to a red rose, with a bubble at the centre. It\u2019s actually the Bubble Nebula, or NGC 7635, and it resides approximately 8,000 lightyears away in Cassiopeia. The data was mostly acquired in late 2022, but I added some from 2021 to pull out some extra detail.\u201d<\/p>\n\n Equipment: <\/span> ZWO ASI1600MM camera, Orion 8-inch f\/8 Ritchey-Chr\u00e9tien astrograph reflector, EQ6 mount Tom\u00e1\u0161 Slovinsk\u00fd, Kosice, Slovakia, 8 December 2022<\/strong><\/p>\n\n Tom\u00e1\u0161 says: <\/span> \u201cShooting was quite tricky, especially because of the weather. But a few minutes before the event, clouds above my backyard disappeared, only to reappear a few minutes after it had ended.\u201d<\/p>\n\n Equipment: <\/span> Canon EOS R6, TS-Optics 1,000mm Newtonian, Sky-Watcher Star Adventurer, Leofoto Summit LM-405C tripod Davy Viaene, remotely via the E-EyE Observatory, Spain, 3 and 8 November 2022<\/span><\/strong><\/p>\n\n Davy says: <\/span> \u201cIn autumn, the Andromeda Galaxy, M31, reaches high altitudes and is visible all night, which makes it ideal to aim at. The combination of telescope and camera makes it possible to frame the galaxy in one shot. In post-processing, I slightly changed the natural colours of M31\u2019s outer parts, making them more blue. The technical challenge is always fun.\u201d<\/span><\/p>\n\n Equipment: <\/span> ZWO ASI6200MC Pro camera, Takahashi FSQ106ED III refractor, Paramount MyT robotic mount<\/span> Pat Devine, Edinburgh, 20 and 25 November 2022<\/strong><\/p>\n\n Pat says: <\/span> \u201cI took up astrophotography in 2020 and joined the Edinburgh Astronomical Society, taking advantage of their online resources. I have seen pictures of the iconic Horsehead Nebula since I was a child, so it was one of the first targets I wanted to try to capture when I started imaging. I used narrowband filters to deal with the light pollution.\u201d<\/p>\n\n Equipment: <\/span> ZWO ASI183MC Pro camera, Celestron 8-inch Rowe-Ackermann astrograph reflector, Sky-Watcher HEQ5 Pro mount Francis Bozon and Jean-Luc Gangloff from Team ARO, remotely via Alentejo Remote Observatory, Portugal, 4 August\u201328 September 2022<\/strong><\/p>\n\n Francis says: <\/span> \u201cThe Dumbbell Nebula is a planetary nebula located in the constellation of Vulpecula, about 1,227 lightyears away. It was discovered by Charles Messier in 1764 and is numbered 27 in his catalogue. Looking at M27 is like looking at the end of our own Solar System in five billion years\u2019 time.\u201d<\/p>\n\n Equipment: <\/span>Moravian G3-16200 camera, Astrosib RC 400 Ritchey-Chr\u00e9tien reflector, ASA DDM85 direct-drive mount![\"\"](\"https:\/\/c01.purpledshub.com\/uploads\/sites\/77\/2023\/01\/2f0df9e9-ca79-4fc4-a68a-a5834a28e9c9.jpg\")
