The Dragon's Egg Nebula.
This nebula in Norma is close to the famous "Fighting Dragons of Ara" hence its name. Captured from my Bortle 7-8 backyard in Sydney. This received a Highly Commended in the recent Astrophotography Prize & a top-pick on Astrobin: www.astrobin.com/qkmfea/ 🔭 #astrophotography

It was cloudy last night, so this is not the Harvest moon/super-moon, but instead the full moon from last month just before, and during, the total lunar eclipse.

Yes of course! I'm paying the price now for the lack of sleep (and I've still got telescope & camera pieces strewn everywhere)

Quick snap of this morning's total Lunar #eclipse. Taken with a Samsung Galaxy 21FE smartphone attached to a Skywatcher ED80 with 2x Powermate. 🔭 #astrophotography #bloodmoon

I will probably try and capture tomorrow morning's total #lunareclipse from my backyard. In the meantime, here are a few of my best lunar eclipse images from the last few years. Good luck to everyone planning to view or image the eclipse. 🔭 #astrophotography

Small talk is easy when you're an AI generated representation of a human. For example, you can talk about how you only have four fingers on your left hand. 🙄 Honestly, Google "Discover" serves up some dross. #FuckAI

Fenrir, the Dark Wolf (SL-17).
This dark nebula is named after the monstrous wolf from Norse mythology. I captured this from my Sydney backyard during a batch of good weather in late June. 6 hours of Ha (ALP-T filter), with 30 minutes of colour (L-Pro filter) for the stars. 🔭 #Astrophotography

An outer filament of the Eta Carina Nebula. This is on the South-East edge of the Nebula & is usually excluded from most images of Eta Carina as it won't fit in most fields.
This is a HOO image (Ha & OIII) using an Antlia ALPT filter, Skywatcher MN190 telescope & ZWO 2600mc. 🔭 #astrophotography

Last night's full-moon above (part of) the Sydney Harbour Bridge. This is not the photo I was after - I wanted to catch the Moon rising behind the bridge, but clouds on the horizon stopped that! Just a very quick edit to bring up the dark foreground. Pentax K-5/ED80 1/180s ISO560 🔭 #astrophotography

Hope you don't mind another one, Robyn?
I bought one of these on ebay for my 20+ year-old, Global knife set. I wasn't sure if it would work but have been very pleasantly surprised. It doesn't require much pressure; you just pull the knife slowly through each of the wheel slots a few times.

The moon one day after first quarter. This was imaged with a Samsung S21 smartphone and a 37 year-old telescope.
This is actually my first astro image of any kind since September last year. Telescope is an 80mm Mak-Cass f10. Stacked the best 25% of 1600 UHD video frames. 🔭 #astrophotography
