Eta Aquariid, Twilight, Sunrise, Sunup

6 May 2020
A photoblog.
The astrophotography is single shots and I have posted mainly for the meteors that are captured in them. They all have at least one meteor except one, which has none.

In the footnote below is more about Eta Aquariid for those that are interested, with links to web pages for more information.

There is no meteor in this one, but there is a windmill and a tree, for perspective, as well as the Milky Way.

There was a lot of experimenting in the astrophotography editing. Still learning and twigging.

The challenge of the light. The stars are always in the sky, just that the sun’s light trumps their sparkle.

The golden glow of dawn. Looking south.

The western sky at sunrise.

There she blows.

Sunlight through a coolibah and dancing on the ground cover. I like my “yellow brick road” I wonder where my wizard is?

Playing with light is so enjoyable.

Badboy and I got lower and the sun got higher and the view changed.
Looking east….
…looking west. With a crow perched on the windmill letting his unmistakable call to be heard.

Eta Aquariid from Wikipedia also spelt Eta Aquarid


Named After Aquarius 

The radiant, the point in the sky where the Eta Aquarids seem to emerge from, is in the direction of the constellation Aquarius. The shower is named after the brightest star of the constellation, Eta Aquarii.

The Eta Aquarids is one of two meteor showers created by debris from Comet Halley. The Earth passes through Halley’s path around the Sun a second time in October. This creates the Orionid meteor shower, which peaks around October 20.

Comet Halley takes around 76 years to make a complete revolution around the Sun. The next time it will be visible from Earth is in 2061.

From ABC Science Genelle Weule
The Eta Aquariids meteor shower is created as Earth passes through the dust trail laid down by Halley’s comet.

Halley’s comet circles in towards us every 76 years from somewhere out beyond Pluto.

While it was last in our skies in 1986, the dust we are passing through is tens of thousands of years old, said Jonti Horner, an astronomer at the University of Southern Queensland.

And because it’s so old, it’s had time to spread out.

“So we cross through this meteor stream for more than a month from April 19 to May 28,” Professor Horner says.

We cross the stream again in October, which is when we see the Orionids meteor shower.

But Eta Aquariid meteor shower is more impressive because we pass through the guts of the dust stream during the peak so the rate of meteors is much higher.
