Orion Nebula 14/01/2012 Orion Nebula 14/01/2012, originally uploaded by purpleface.

The weather over the past few days has been amazing. Lovely crisp blue skies, amazing sunsets & wonderfully clear night skies. And I've been using this to my advantage, taking as many photos of the stars as I can.
I had the idea to photograph the Orion Nebula (see above) for a few nights but I was waiting for the sky to become fully clear. I first photographed the nebula when the sky was hazy & the full moon was casting its glow across most of the sky. The photograph I got on that night was amazing (to me, it was amazing, obviously it's not amazing to those with epic telescopes & satellites deep in space ;p) & it surprised me because I never expected to be able to capture a photograph like this. I thought it was reserved for people with powerful telescopes!

I made a pact with myself that I would go out there again when the moon wasn't due to rise until 3am & when there was less haze around.

That night happened a few days later. It was -2 & there was frost on the ground so I wrapped up extra warm & took the camera out to cool (tell me if I'm wrong but letting the sensor cool on your camera helps reduce noise...I think). After a little while I started to photograph the nebula using various different settings. Now, you all know that the earth spins, this is what gives us night & day. Therefore, if you set your camera up to expose for 30 seconds, you're going to get light trails instead of a still (for want of a better word) image. As my camera ISO goes up to 12000, I stepped it right up & I exposed for 3.2 seconds. For me, this is the best way to be able to capture a still shot without using a tracking device. I did, however, find that ISO 12000 was too noisy so I stepped it down to 5000. And that seemed to do the trick. I imported the shot into Lightroom, tweaked around with some settings & this is what I came out with.

I used a Canon 7D with a 90-300mm lens.

I'm pretty happy with it. Next step is to get a new mirror for the telescope (we accidentally knocked it over & the mirror smashed inside) & an adapter for my DSLR. Then we'll be away!
