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! Hope you enjoyed this post, thanks for reading.

Sorry, didn’t mean to double post, the first time I got an error. you can delete one of them.
Brilliant photo! Love it!
I just got my first dslr (canon 1100D), mind if I ask you some questions? Do you zoom in or leave it on 90mm? Manual focus I presume? What f number do you set it to?
Any help greatly appreciated, I haven’t managed to get any good photos yet.
i think it’s a fantastic photo!! I’ve photographed Orion with my bridge camera but recently got my first dslr. Mind if i ask you…did you zoom right in or leave it on 90mm? I presume you use manual focus? What f no. should you use? Any help appreciated!!
Hi there Mac!
I zoomed to 300mm & used manual focus – I had to try this a few times before I got it correct.
I used f/5.6 for this shot particularly but anything above that would be sufficient; you would obviously have to adjust your settings to compensate. You don’t want to go to wide as this might make focusing slightly difficult although it may benefit you if you are finding your photos are coming out too dark & noisy.
Thanks a million for your advice Sarah, I really appreciate it. I hope the weather clears here (Ireland) so i can get out and experiment.
I’ve taken some pics of Orion such as this one: http://pix.ie/maca/2112731/size/800 with my bridge camers but am finding it more difficult to get anything nice with my dslr.
