This 3D stereoscopic image can be seen by those lucky enough to control their eyes enough to merge these two images into one in the middle, by going cross-eyed.

The left image is taken by Paul Stewart in New Zealand, and amazing astronomer. At the same time, I took the image in the right on the east coast of Australia, around 9:30pm AEST using a 9.25 SCT telescope. The slight separation is only just enough to give a small sense of depth around the edges where the shadows and the craters reveal the curvature of the full moon. It is subtle and would work better with more separation geographically, or taken from space.

Still, it is a fun experiment to try if you have a friend to coordinate with some way away from you!

Here is another photo from the weekend of the observatory as the clouds parted for a moment. The guys at the site and the booking agents liked this photo enough to put it on their website! If you would like a romantic nerdy weekend (was that an oxymoron?) be sure to check out the cottage and astro tour they offer.

This weekend I had the pleasure of visiting the Blue Mountains Observatory in Leura, NSW. Unfortunately despite staying for 3 nights during the moonless lunar phase, the site was covered by cloud, fog and rain the entire time. The only exception was 1 hour around 1am on the second night, by which time I was sufficiently inebriated enough to make operating my camera equipment fairly challenging. I managed to get a few decent shots that even the real (qualified) astronomers told me they enjoyed. This star trail photo is an old fashioned 11 minute single exposure at 16mm / f.28 / ISO 1600. There is some cloud behind the dome illuminated by Katoomba light pollution but the middle of the image is the glow of the milky way itself which runs horizontally across the image. I will post another version without star trails soon.

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.

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.
