Space Weather – October
October 2021 sees a new Moon on the 6th, the perfect time to observe and image under dark skies. While our orbit around the Sun takes us further away from the largest gas giants in the Solar System, they’re still spectacular in the night sky. Saturn has a close encounter with the Moon on the evening of the 14th Oct and Jupiter on the 15th Oct. Head outside just after dark to enjoy.
Late October is also when our closest major galactic neighbour, the Andromeda Galaxy can be seen low on the northern horizon under dark skies. It shows up as a large fuzzy patch in binoculars or if conditions are good, visible with your eyes alone. At BINTEL we often get asked what’s the furthest thing you can see. At 2.5 million light year away from the Milky Way, the Andromeda Galaxy is it!
The month of October continues to bring warmer weather and from what we’ve seen so far, an increase in storm activity right across the country. With warmer weather and humidity comes dew, one thing that can totally ruin an evening under the stars. We’ve put together an article on preventing and dealing with dew and the range of dew control products BINTEL carries here.
We’ll hopefully see states around Australia emerge from COVID-19 lockdown during October. This will include the re-opening of the renovated BINTEL retail showroom. We thank all of our customers for their patience during these very difficult times.

Photoname: Natural Narrowband Trifid
Details: The Trifid nebula, aka M20 or NGC 6514 is a popular and bright nebula about 4300 light years away in the constellation Sagittarius. This image was an experiment with the aim to use 7nm narrowband filters to create a natural colour looking image. The difference between conventional narrowband imaging (using SII, Ha and OIII filters as RGB), I captured a few hours of subs through a Hydrogen beta CCD filter instead of SII, and combined the narrowband channels in the order Ha, OIII & Hb as RGB. Imaged through a 8″ SCT at f6.3 using a QHY268M camera, for a total exposure time of 9 hours and 5 minutes.
