Moon gazing and the spaces between

An evening late for the super moon (being a mother does not pause for a super moon), I wrestled the telescope out under a clear Spring night sky and managed a few shots and some video with my DSLR mounted to the telescope. I am too aware that I could muck about with stacking to improve these, and I did start, but then reality of having finite time and requiring actual sleep before a day at work (she notes, meanwhile typing a blog post after midnight) took hold, so my RAW images were processed on wait for it….my little dinky chromebook.

I do really favour staying low tech with astronomy though. My favourite image of saturns rings were taken on my iphone  held up the telescope eye piece many many years ago. I have a 10 year old 90mm refractor telescope, on an equitorial mount with no fancy goto or tracking. The thumb screw is missing from my eye piece because I dropped in in the dark. I am always tripping over the tripod legs in the dark.  I have light pollution in my yard from neighbouring houses and street lights. Astronomy and astrophotography doesn’t always need to be a perfect science.

It’s about connecting with that vast beautiful amazing expanse of worlds up there. We generally, I think, take it for granted. When people talk about mindfullness and mental health, being centred or connected,  there is rarely mention about getting outside for a look at the night sky and getting to know it. It’s a humbling and profound place though, looking up in the dark.

So, in all my imperfection, and clumsy technique, I still see the moon’s perfection captured in my photographs:

aboriginal night skies

I also want to mention quickly, about the incredible learning adventures I am having by reading Aboriginal Astronomy by Dr Ragbir Bhathal (2010) which I borrowed through my local library.  I found it via a subject search for aboriginal astronomy as although I had found a fantastic list of further reading here on an Aboriginal Astronomy website, many of these weren’t a bit tricky to find easily in my speedy searches.

It’s a simply bound document publication,  which belies the astounding reading inside.  A mind-opening insight into sociocultural/ethnoastronomy and it’s not often you gain a whole new world of insight in just the first few pages of something.  I’m in awe of the deep connection of the cosmos expressed in examples of indigenous scientific understanding of the night sky and the expression of this understanding through stories, songs and art.

When I look at aboriginal art I’ve had for years right next to my desk, I really thought I appreciated their complexity. But, I now see something even more, and much different, something else,  after only a few pages reading this book. Not only is this shift in understanding, something I can see in indigenous artwork, but when I look up into that great canvas of the night sky – my imagination is unlocked somehow.  It’s a small insight into how to to try to unsee the known and familiar patterns, and to instead, see the sky through wizened ancient eyes. It’s galaxies of art, science, and history colliding with energy.

We can never truly see the full story though, which is sacred and rightfully respected and shared in a way that deep and cultural learning should be.  Just a glimpse though, is enough to give you a sense of how unique and special indigenous australian relationship was with the night sky.

You can get a taste of the publication, in this shorter document available online  Astronomy of the First People of Australia by Ragbir Bhathal, but I encourage you to seek this out.

For now, I will just continue to wonder and dwell on the realisation that it really is all about the spaces in between.

Corona Australis, the Southern Crown constellation is clearly visible in this photograph I took last week. But now I begin to see something else even more beautiful…

One small step for astrophotography

I recently unpacked my telescope for the recent lunar eclipse:

 

 

 

 

 

and had been to a planetarium movie with my daughter. That was me enchanted again.

Having had a few interesting attempts at astrophotography back in 2005 with a point and shoot camera and my telescope, for a bit of quick self- inspiration, I managed to get a fuzzy rings of Saturn on my mobile phone camera through my 90mm Sky Watcher scope.

It’s not fantastic quality, but this is another world, a ringed planet, the most beautiful and amazing of icon of the vastness of our universe, via a phone camera. It’s sort of cool. This has now inspired me to to go a bit further and hook up my DSLR with my scope, and use a laptop to control some of the exposure and press the shutter remotely, to avoid wobbling the telescope.

Gear

I already had the telescope and camera, and just needed a relatively cheap ($AUS 30) t-ring which connects the camera, and I new Barlow lens which had a removable magnification piece ($70).

You then attach the t-ring and the Barlow lens to the camera (make sure you remove all the  covers first – I had a bit of a dumb moment) and then attach the camera into the telescope eyepiece. I then dusted off my archived IBM T20 Thinkpad (I knew I had been keeping this for a special occassion). I also downloaded the Canon EOS Utility software, because my CD was long lost, hooked up a cable and this gives you the functionality to take photographs and change exposure from your laptop.

What spacey photographs to try first

The most straightforward guide that I have found is Phil’s Astronomy Blog and his simple Tips and Tricks for Astrophotography.  I’m basically going to try capturing exactly what he suggests :

1) stellar dust, star clusters and smaller nebulas in the Milky Way

2) some star trails

Both of these approaches teach you something about exposure for the night sky and a little go at stacking multiple images, which is pretty key to some of the really cool star trail photos you see around.

Now I just need a clear night and some time!
