The next biggest prawn in my life besides the iconic Ballina roadside icon (now a Bunnings), IC 4628 is captured here in it’s natural red/pink prawn palette. Using the hydrogen as the main luminance, or detail layer, you can see how far much of the dust and gas go – right to the edges of the frame. A cluster of newborn stars float out of the chaos in the middle where gravitational forces churn the material into these hot, bright new members of the system.

I've discovered it may be the CCD chip itself causing the slight focus issue to occur on one side of my colour images. It's not a problem when I do HaRGB combos but would be nice to correct once and for all. Omega Centauri here taken in 30s exposures last night using RaSA and Qhy12 unguided.

It was clear and moonless for long enough tonight to get the 40 or so minutes of REAL colour photographed for this NGC6188 .. not false colour narrowband this time! You may be able to see 2 creatures fighting which is why it's called "The Fighting Dragons of Ara". I like to think of it as "The Creation of Adam" .. or maybe "Atoms" would be more appropriate. Taken with 11" Celestron RASA and Qhy12 cooled colour CCD. #celestron #starstuff #startalk #celestronrocks #visitnsw #byronbay #nsw #australia #astronomy #astrophotography #astro #ig_astrophotography #abcopen #abcmyphoto #photographingspace #celestronrocks

Another narrowband image taken under the bright moon, using filters to cut through and catch the photons I need, to see IC 4628 - The Prawn Nebula! Where I live in Australia we have an iconic giant prawn roadside attraction so I feel like this is our local nebula :) Rich in Hydrogen (Blue) and Sulphur (Green) but fairly weak in Oxygen (Red), mapping this way as HaRGB shows a beautiful etherial cloud. Total 100 minutes using Celestron 11" RASA, CGX and QHY9m. #astrophotography

Same as last post (Fighting Dragons of Ara - NGC6188) but I swapped scopes for a closer look at the core emission which is rather pretty! #astrophotography

The Fighting Dragons of Ara (NGC 6188) is a beautiful, large emission nebula currently above us in the Southern Hemisphere in the early evening. Photographed last night in narrowband, the oxygen is seen as blue and the hydrogen as green. The long tendrils of dust and gas stretch and swirl into core where bright new stars are birthed into existence, each with their own solar systems, planets and moons. 42x1m Ha + 20x1m Oiii + 30x1m Sii (Celestron RASA, CGX& QHY9M) #astrophotography #celestronrocks

Yay! I got my first illuminated transit of the International Space Station across the crescent moon! Taken less than an hour ago from Byron Bay @ 17:51:07s using C9.25" Edge HD / F10 / Canon 70D / ISO 1800 / 1/1600s - 7 Frames #astrophotography #celestronrocks

A little subtle HDR Earth shine composite taken with the cheap Celestron 4SE and Canon 70D. I think the time has come to upgrade my camera body soon for this lunar stuff. The results are so much better through the 9.25" Edge HD but even this cheap and cheerful setup (Canon 70D + 4SE), which is probably about $1k total if you shop around, yields decent (and portable) results.
