Hi everyone
Please find this month’s news, research and Star charts attached.
Astrophotography weekend
Planning is underway for another enjoyable weekend of Astrophotography at the usual Foxton Beach venue. Accomplished photographers
are keen to share their knowledge and experience.
The event will be held 25 thru 27 November. This will be the eighth New Zealand Astrophotography Weekend hosted by HASI. Is become a popular
annual event dedicated to astrophotography in a wonderful dark-sky location. Its open to everyone interested in astrophotography from beginners
to advanced. Come along and share your knowledge, tips and experiences. For more information visit our HASI Web site www.horoastronomy.org.nz
Astrophotography includes many styles and each with different gear. What do you think about when you hear the word ‘astrophotography’? You might
think of the James Webb Space Telescope and its incredible close-ups of nebulae and galaxies far away. Or perhaps you think it's more to do with
images of the Milky Way, the moon or the southern lights. Astrophotography means all kinds of things to photographers, from landscape photography
at night to the more technical pursuit of deep sky close-ups using telescopes and planetary cameras.
Astrophotography is becoming more popular and accessible in all of its guises. Photographing the deep sky is now surprisingly easy.
Armed with a DSLR or mirrorless camera on a tripod-mounted tracker, even novice Astrophotographer’s can capture great shots of star clusters,
nebulae, galaxies and other deep-sky objects. This is thanks to a new generation of simple equatorial mounts designed for cameras rather than telescopes,
which allow a simple tripod-and-tracker setup that’s both affordable and portable. When starting you will need clear skies and a dark location,
ut astrophotography also requires good ‘seeing’ (a lack of atmospheric turbulence) and ‘transparency’ (a lack of the moisture and dust in the air that
typically occurs after heavy rain). The upcoming HASI Astrophotography weekend is a good place to learn more about the subject.

APOD: Two Comets in Southern Skies (2022 Oct 08)

Explanation: Heading for its closest approach to the Sun or perihelion on December 20, comet C/2017 K2 (PanSTARRS) remains a sight for telescopic observers as it sweeps through planet Earth's southern hemisphere skies. First time visitor from the remote Oort cloud this comet PanSTARRS sports a greenish coma and whitish dust tail about half a degree long at the upper left in a deep image from September 21. It also shares the starry field of view toward the constellation Scorpius with another comet, 73P/Schwassmann-Wachmann 3, seen about 1 degree below and right of PanSTARRS. Astronomers estimate that first time visitor comet C/2017 K2 (PanSTARRS) has been inbound from the Oort cloud for some 3 million years along a hyperbolic orbit. Schwassmann-Wachmann 3 is more familiar though. The periodic comet loops through its own elliptical orbit, from just beyond the orbit of Jupiter to the vicinity of Earth's orbit, once every 5.4 years. Just passing in the night, this comet PanSTARRS is about 20 light-minutes from Earth in the September 21 image. Seen to be disintegrating since 1995, Schwassmann-Wachmann 3 was about 7.8 light-minutes away.
