Sun today. Featuring some scattered activities on the surface. The plage near the center looks like an X. #astrophotography #sydney #australia

Omega Centauri. Right next to Centaurus A. A globular cluster that appears as big as the moon... Provided you are in a place with a dark enough sky. (I've been to a bortle 2, though not present then other clusters like Pleiades is very visible) #astrophotography #sydney #australia

Antennae Galaxies. A pair of galaxies in mid-collision, which is what we can expect when we merge with Andromeda in the future. At 4 hours data, need more so the tails can be really visible. #astrophotography #sydney #australia

Trifid Nebula. Early morning target, with just an hour data. Scheduled to be photographed after the main target last night and just before sunrise. #astrophotography #sydney #australia

The main target last night, Centaurus A. Edge on galaxy that was discovered right here at Parramatta some time back. 5 hours worth of data. Thankfully captured successfully, even surviving the meridian flip :P #astrophotography #sydney #australia

Happy Pi Day! Just a simple photo of Orion, without any filter. Orion is ~1,344 light years away... no obvious Pi there, but I love it when cosmic measurements accidentally line up with fun numbers. #astrophotography #sydney #australia

Hot and humid day here today. #astrophotography #sydney #australia

Cloudy Totality #astrophotography #sydney #australia #moon

This is probably the peak, it's getting brighter now... Provided the clouds get out of the way! #astrophotography #sydney #australia #moon

Got another shot! 10 frames of 2 second subs stacked. #astrophotography #sydney #australia #moon

The clouds cleared just enough to get this. Hope I get more shots. #astrophotography #moon #sydney #australia

My #solar photo for the day. More prominence activity, and that big plage connecting two sunspots. I put the relative size of earth as the dot in 'j' of 'jromz03'. :) #astrophotography #sydney #australia

92% Waning #Moon. Taken around 10:30pm, rising from the east. Noticed that Jupiter is still eye catching-y bright every night. Even after opposition last month. #astrophotography #sydney #australia

My solar photo for today. Big plages that seems to be combining near the center bottom (still at least 10x the earth). A few low prominences, filaments, and sunspots to see. Also, today's my youngest's 18th birthday. Where does the time go? #astrophotography #sydney #australia

My solar photo on this hot day. This calls for some coke and vanilla ice cream. #astrophotography #sydney #australia

Happy New Year! Aircon broke (some motherboard issue with either indoor unit or compressor), and we have upcoming heatwave days this week. Need to make heaps of ice cubes then. #astrophotography #solar #sun #sydney #australia

Happy birthday to my favorite #cobberdog!

Hey, it's a full moon tonight! #astrophotography #sydney #australia

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) #astrophotography #sydney #australia

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. #astrophotography #moonhour #sydney #australia

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. #astrophotography #sydney #australia

#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.) #astrophotography #sydney #australia

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. #astrophotography #sydney #australia

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

Animated GIF of Blood Moon earlier. I need coffee... #astrophotography #sydney #australia

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. #moon #eclipse

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. #astrophotography #sydney #australia

#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. #astrophotography #sydney #australia #moonhour

"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. #astrophotography #sydney #australia

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 #astrophotography #sydney #australia

Lagoon Nebula. Relatively young giant emission nebula (plus cluster), estimated to be just a few million years old. Yeah, so a baby. #astrophotography #sydney #australia

Jewel Box Cluster. About 6,400 light years away. Naked eye visible in dark skies, though looks like a hazy patch. #astrophotography #sydney #australia

#Sun today. Heaps of prominences jumping around. #astrophotography #solar #sydney #australia

Messier 22. Used #seestar #S50 in equatorial mode. Captured 45 mins worth of subs. Then processed manually in Siril/GraXpert. #astrophotography #sydney #australia

Helix Nebula or the Eye of God. One of the closest planetary nebulae. There should be a dying white dwarf in the middle. Generally a good DSO target for both beginner and seasoned astrophotographers. Despite being fainter, it's a tad bigger than a full moon! #astrophotography #sydney #australia

The Fighting Dragons of Ara. A star forming region that's about 4,000 light years away. Not that far 😛 Also a favorite target among astrophotographers. #astrophotography #sydney #australia

Omega Centauri. The largest and brightest globular cluster in the Milky Way. Really old cluster (12 billion), with a (predicted) massive black hole in the center. To keep them all together. Star hopping is definitely a thing for any civilizations there, if any. #astrophotography #sydney #australia

The Great Peacock Globular. The fourth brightest globular cluster in the night sky. It's naked eye visible on dark skies (maybe bortle 3 or better). For some reason space telescopes like to use this cluster for their calibration steps. #astrophotography #sydney #australia

Eagle Nebula or Messier 16. Home of the famous Pillars of Creation. It is 7,000 light years away, so we're seeing what it looks like 7,000 years ago. There's speculation that the Pillars are already gone, we're just seeing a 'delayed broadcast'. #astrophotography #sydney #australia
