Still working out the kinks in my workflow, but here is a decent stack of exposures from my driveway of the Table of Scorpius region which is filled with all kinds of crazy star clusters, nebula, dust clouds, gas and basically anything you can imagine. If you held up a business card at arms length at the sky, that is about the size of what you are seeing here. The word space is probably a misnomer in some regards. It is pretty full really.

NikonD5100 piggybacked on Celestron 4SE / Several x 30s, ISO1600, f2.2, 50mm prime.

Otherwise known by the media as the (sigh) supermoon. The difference in size is really quite minor and does not make a huge difference to the casual observer. Honestly, every full moon is pretty wonderful regardless. Most astronomy nerds who have to put down their telescopes for a few weeks waiting for it to go away know it better as the stupid moon.

Captured here with a 9.25" Celestron SCT in thin cloud unfortunately, but it turned out ok. 1/1600s / F11 / ISO 100.

My New Zealand readers might be familiar with the big kiwi bird in the Sagittarius region of the milky way. Can you see it? It looks kind of like a big ball sack to me but I can go with kiwi bird, sure.

This tiny patch of the milky way is dominated by Antares, the bright orange star on the left. Dark wispy tendrils of gases and clouds in this area are star-forming nebula that are so large, I can photograph them with a regular DSLR 55mm lens as done here.

This image is made from 20 x 30" exposures stacked together to draw out the cloud definition. The camera was piggybacked to a telescope that was tracking the sky rotation so the stars would not streak.

This is my first attempt at the Lagoon Nebula (M8) and after much fiddling and cursing in the dark I managed to grab a few short frames that were relatively ok. About 4 or 5 exposures stacked together. Though not as sharp or detailed as I would like (the view slipped behind a tree just as I was fine tuning my equipment), Nebula are easily my favourite targets in the sky. The colours here are natural, just as my RGB camera captured them. The diffraction spikes however, are added in post processing for that classic retro star shine that older lenses and equipment would produce. Interestingly, they still feature regularly in NASA and award winning astro imagery but are not captured by modern telescope optics!

Hello there little meteor! You flew through the universe for aeons and came into my life briefly, until my planet burnt you to a crisp before you even had a chance to say hello. Now nobody knows you existed except for the small photons you deposited into the CMOS chip on my Nikon camera. Such is life.

Here is the view from the lookout at Coolamon Scenic Drive, just before the turnoff to Byron Bay. That is, if you look up, and not out.
