PHOTO OF THE MONTH
The Crescent Nebula
Andy Weller, Sandy, Bedfordshire, 16–17 July 2021
Andy says: “I’ve only been doing astrophotography for a year, starting during lockdown – as many people did. This target always appealed to me because of its jarring resemblance to a human brain just hovering in space. Its interesting layers of gasses give it an almost ghostly look and feel.”
Equipment: ZWO ASI294MC Pro camera, Celestron C11 XLT Schmidt-Cassegrain, Sky-Watcher EQ6-R Pro mount
Exposure: 73x 4’, gain 120
Software: PixInsight, Affinity Photo, Topaz DeNoise
Andy’s top tips: “The Crescent Nebula is full of fine detail, so try to retain as much as possible while not allowing noise (unwanted artefacts) to dominate. I spent a good third of my time on noise reduction. Because of light pollution from LED streetlights, I used a 7nm dual-narrowband filter to capture the Ha (hydrogen-alpha) and OIII (oxygen) wavelengths, and I constructed shields around my scope to create shade.
I experimented with colours by splitting out and recombining the Red, Green and Blue channels until I struck upon the look and feel I wanted. Don’t be afraid to experiment; in the worst case scenario you just start again.”

The Heart and Soul Nebulae
Simon Todd, Haywards Heath, November 2020–February 2021
Simon says: “This two-panel mosaic is the first I’ve tried with this camera. I stacked each panel and then used the ‘Mosaic Tool’ in Astro Pixel Processor to merge them into a mosaic just short of 100 megapixels.”
Equipment: ZWO ASI6200MC camera, SharpStar 15028HNT astrograph, Sky-Watcher EQ8 Pro mount
Exposure: 101x 300” per panel
Software: Sequence Generator Pro, APP (Astro Pixel Processor), PixInsight
The Sun at perihelion and aphelion
Andrei Dumitriu, Bucharest, Romania, 2 January and 5 July 2021 .
Andrei says: “The perihelion and aphelion dates printed in your January issue (in ‘The Sky Guide’ on page 44) inspired me to capture the 3 per cent size difference between the ‘two’ Suns. January’s perihelion Sun is on the left and July’s aphelion Sun is on the right.”
Equipment: ZWO ASI178MC camera, Orion ED80 apo refractor, Sky-Watcher Star Discovery mount
Exposure: 0.9ms, gain 0 (perihelion); 0.3ms, gain 97 (aphelion)
Software: AutoStakkert!, RegiStax, Photoshop
Early Perseid passing close to Jupiter
Steve Brown, Stokesley, North Yorkshire, 3 August 2021
Steve says: “Having had no luck catching early Perseid meteors, I repositioned my camera to take some shots of Jupiter. I’d just hit the shutter release on a test shot when the meteor appeared, resulting in this very lucky capture.”
Equipment: Canon 250D DSLR camera, Canon 50mm lens, Camlink TP-2800 tripod
Exposure: ISO 1600 f/2.0, 5”
Software: Photoshop
Mineral Moon
Neil Corke, Moraira, Spain, 22 July 2021
Neil says: “This was my first attempt at astrophotography and I’m really pleased with the result.”
Equipment: ZWO ASI2600MM camera, Williams Optics FLT 132 apo refractor, Paramount MX mount
Exposure: 300” video
Software: FireCapture, AutoStakkert!, PixInsight
The North America Nebula
Rachael and Jonathan Wood, Doncaster, 15 June 2021
Rachael says: “I’m a fan of the Hubble Palette, so I used a one-shot camera and an L-eNhance filter to split Ha and OIII wavelengths into individual channels; then I colourised and combined them with a green made by blending the Ha and OIII layers.”
Equipment: ZWO ASI294MC Pro camera, Sky-Watcher Evostar ED80, Sky-Watcher HEQ5 Pro mount
Exposure: 2h 10’ total
Software: Astro Pixel Processor, Photoshop
