Happy birthday to my favorite #cobberdog!

Hey, it's a full moon tonight!

#astrophotography #sydney #australia

Buy a few if you have multiple setups. Saves time of moving one to another.

The #sun in this glorious Sydney arvo.

The true color of the sun is white, since it emits the entire visual spectrum equally. It's only in Earth where light get scattered on our atmosphere.

(I capture the sun in B/W, and apply color in post)

The near side of the #moon (the one facing us) looks smoother because it got "paved over" by lava billions of years ago, while the far side stayed rough and battered.

Found more data and reprocessed to get a bit brighter one.

Dammit, that's why the 3rd target failed overnight. I forgot to set the 'goto target, center, start guiding' option!

Skull Nebula. A planetary nebula with a triple-star system at its center. A nebula of just a few thousand years, a cosmic blink compared to other DSO.

Personally, I call this The Metroid nebula instead. 🎮

#astrophotography #sydney #australia

Jellyfish cluster, or Messier 30, or NGC 7099. A cluster as old as the Milky Way, roughly 27,000 light years away from us. Best viewed between August and September. Unusual because it has heaps of blue younger stars, compared to its age.

#Saturn will be in opposition starting tomorrow. Excellent time to observe this planet, weather permitting.

(Celestron C90Mak + ASI178MC + 2x Barlow. Top 5,000 frames out of 15,000.)

Messier 11 or the Wild Duck Cluster. They say it looks like a flock of ducks on a V-formation when viewed from a telescope. An old cluster, estimated to be 220 million years old. Unusual because usually cluster would have drifted apart by then.

Sunday #solar photo. A tad unremarkable on the Ha spectrum.

Animated GIF of Blood Moon earlier.

I need coffee...

End of Eclipse started.

Yay!

#astrophotography #sydney #australia

Stars are now visible, increased exposure time.

#Eclipse is getting red.

Progress so far of the #eclipse.

Eclipse is starting... A few clouds but overall clear. Setup is focused and capturing.

A look at the other participant in tonight's cosmic event. Yeah, the #sun. Hopefully, it we will have a good field of view this early morning. I'll definitely be losing sleep.

Arrow pointing at Earth. It's the dot in 'j'. Yeah. we're that small.

#Moon at before 8pm tonight.

It's really fascinating that as the Sun is 400 times larger than the moon it is also 400 times further away as well. That's why for now the moon can cover the sun. Not so in a few million years.

i'm into astrophotography.

yes

"When the moon is half full… Does that make it an optimist or a pessimist?"

#astrophotography #sydney #australia #moon #moonhour

NGC6770. Stopped recording after a new minutes, this target will need very long capture time and probably best with a mono like my minicam8 instead of a OSC.

Looks like using filters on clusters wash out the natural colours. Post need little more effort to bring them back.

Tarantula Nebula. Named because its web-like filaments of glowing gas, seen in telescopes, resemble the legs of a giant spider.. At about 1,000 light-years across, it’s the largest and most active star-forming region
#astrophotography #sydney #australia

Orion Nebula! 😃 It's now a visible target... But still close to sunrise.

#astrophotography #sydney #australia

String of Pearls galaxy. Named due to its slender, elongated edge-on appearance packed with bright, pearl-like star-forming regions and clusters that run along its disk
