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)

Image Credit & Copyright: Jose J. Chambo (Cometografia)

https://apod.nasa.gov/apod/ap221008.html

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.

Time to Name a Planet

In celebration of 100 years of the International Astronomical Union, the IAU NameExoWorld  global competition allows any country in the world to give a popular name to a selected exoplanet and its host star. New Zealand has been assigned the planet HD 137388b and its host star HD 137388 and we need your help in choosing names!  You can make a submission here between 1 September 2019 and 30 September 2019 (5:00 p.m. NZST). A panel of judges will select the name of the star and the planet by 30 October 2019 and will make its submission to the IAU by the 31 October 2019. IAU will make it’s final announcement in by 31 December 2019 . The winner will then be notified via email. Please note that entries can only be accepted from people living in NZ during the time of the submission.
