An Evening of Astro-Photography
I’m obsessed with the night sky just now. Which is unfortunate as now we’re into BST the night sky is coming at a more unsociable hour. Who’d have thought after a long winter I was going to miss the dark nights? I’ve enjoyed my recent journey into some low level astro-photography, even without a telescope to really start on deep space and planets, with some modest photography equipment it can be an engaging subject to photograph.
A crystal clear sky on any night is a joy to behold, especially if you’re away from heavy light pollution, and it’s even more enjoyable once you get an idea what you’re looking at. Last night (March 26th) was one of those special nights with a conjunction in the night sky, where 2 or more celestial bodies appear close to each other in the night sky. Last night was the turn of a nice thin crescent Moon and Venus to take centre stage.
Unlike the night before when Jupiter and the Moon were in conjunction the sky had finally lost that misty haze of the last few days and the seeing was very good indeed. Without a cloud in the sky it was too good an opportunity to miss.
We’ve all seen the proper astro-photography stuff, those striking coloured images of distant nebula or close in shots of planets which is specialised stuff but with a basic camera setup you can have a great night working these special night sky events into your pictures.
All pictures were taken with a Nikon D7000, on a tripod and fired using a wired remote control, but most cameras would do a decent job with a mid range zoom lens.
This close in shot of the Moon and Venus show’s just how close they were in the sky. This was taken with a Sigma 70-200mm f2.8 and 2x teleconverter, and it filled the D7000’s frame perfectly. 1/60th, f5.6, ISO400 and 400mm. The moon needs a fast exposure to stop the detail burning out as it’s a very bright object, a full moon requires a even faster shutter, luckily Venus is so bright its fine with the faster shutter speed too.
Switching now to a Nikon 18-200mm VRII lens, a general purpose mid-range super zoom, we get a wider view of the same scene. This time though I’ve slightly lengthened the exposure to 1/2s, f5.6, ISO400, -2/3ev and 200mm. The result is lost detail in the bright part of the moon but I’ve picked up the Earthshine instead, the light reflecting back of Earth lighting the shadow portion of the moon.
Pulling back the zoom even further it was possible to include Jupiter in the shot as well. Same settings as the previous shot, but at 135mm. Jupiter is on the lower right of the shot.
It’s all very well shooting the moon and planets on their own, you could do that from your own garden probably, but sometimes it’s nice to get a little context to the shot as well. I was at Blackford Pond in Edinburgh, not long after sunset when I was taking these so a bit of playing about got the 2 planets and the moon with the tail end of the sunset over the pond. 1/8th, f5.6, ISO400, 18mm, -4/3ev.
With the pond so still there were a lot of reflections from the trees but where was the moon reflection? Moving right to the edge of the pond revealed where it was and with a little playing about with the composition and waiting for a swan to move away which was causing ripples I got a respectable shot of the reflection in the pond.
Same settings as the previous shot but -2/3ev and ISO3200. The super high ISO was required to get as fast a shutter as possible to freeze the movement of the gentle ripples in the water to stop the reflection distorting. This isb’t a major problem with high end DSLR’s these days but some old cameras will give very noisy shots at this high an ISO.
Final shot of the night was a closer in view of the reflection, again a high ISO was required and I also switched on the VR on the lens, which you wouldn’t normally do on a tripod but it did help. After many goes, I finally got a shot with a proper moon shape and pin point stars.
To finish up with, here’s a quick shot of the Jupiter Moon conjunction the night before, if you look very close next to Jupiter and around 4 o’ clock there is 2 tiny pin pricks of light, 2 of Jupiter’s moons.
Next time you find a nice clear night and you’re looking for something new to photograph, why not see how you get on with the stars? They are far from the easiest subjects to photograph thanks to the Earth rotation but with a little practice you could be adding extra depth to night landscapes.
