Spring is aurora season, and just before midnight last night a display of the northern lights lit up the sky. Taking a test shot from the window confirmed the alert from my phone app, so I headed out the door. The display had already started to subside once I’d defrosted the car and got to a dark spot. But I got there in time to capture a sequence of 50 frames. Enough for a (very!) short time-lapse…

A meteor can be seen around half way through the time-lapse sequence, just to the right of the Andromeda galaxy. You might need to download the HD version to make it out… Here’s the ‘test’ shot taken before heading out. The display was pretty strong at this point…

Aurora Season: Aurora Borealis from Yorkshire, England

Image details: Nikon D7000Nikkor 35mm f1.8G at f1.8. All shots were 10 second exposures at iso 640. Edited and animated in Photoshop CS6.


Comet Catalina and M101 the pinwheel galaxyI finally had a chance to photograph Comet Catalina after what seems like a solid month of cloud. By chance this happened to be a night when the comet passed close to the Pinwheel galaxy (M101) forming a brief but beautiful conjunction. Catalina is already an attractive comet, with the delicate ion tail clearly separate from the wide dust tail, with the coma a familiar green colour.

Image details: Nikon D7000Nikkor 180mm f2.8 at f2.8. 9 minutes (18 x 30 seconds) at iso 1600. Using didymium filter. Stacked with Deep Sky Stacker and tracked with barn door tracker. Temperature: -1c. Elevation: 5m. Time: 00:30 UT.


The comet is currently drifting through Ursa Major, making it a perfect target for viewers in the northern hemisphere throughout the night. The live sky map below shows the current position of the comet as it begins journey out of the solar system, never to return!

Standing on the shoulders of giants - Orion rises over Helvellyn in the English Lake DistrictOrion rises over the jagged slopes of Helvellyn in the Lake District. The figure standing in silhouette on England’s third highest mountain is dwarfed by the constellation.

Taken from the lower slopes of Striding Edge, a friend wilfully volunteered to stand on the edge of a precipice as a setting crescent moon illuminates the distant snow-capped peaks.

Using the barn door tracker at half speed allowed me to effectively double the exposure time before the motion blur of either the ground and the sky became noticeable.

This technique combined with the altitude and the dark skies of Cumbria helped bring out the classic deep sky objects. The Great Orion nebula, Horesehead nebula and Flame nebula all make an appearance. With a hint of Barnard’s loop just visible.

The really comes into it’s own with this type of wide angle constellation shot. Making the reddish gold of Betelgeuse and the brilliant white of Rigel stand out spectacularly in the scene.

pacman nebula in cassiopeia DSLRThe Pacman nebula is named after the classic 80’s arcade game character, but to me it looks much more like an angler fish! The little nebula (officially named NGC 281) sits alongside the bright yellow star Scheder, inside the familiar W constellation of Cassiopeia.

A surprising amount of detail is captured in the 66 minute exposure taken at 180mm. Using the softon filter to enhance the string of bright nearby stars forms an attractive triangle with the nebula…

Bonus autumn aurora…

For reasons not fully understood, you’re around twice as likely to see an aurora in spring or autumn then in summer or winter. Even a mild solar flare or gust of solar wind from a coronal hole can spark off a display. This was a great example as it took me completely by surprise a couple of nights before taking the pacman nebula shots. I did managed to get a tantalising glimpse of the display through the clouds thanks to some timely twitter notifications..

veil nebula in cygnusThe ragged remains of a 7000 year old supernova explosion make up the Veil nebula in the constellation of Cygnus. A 72 minute exposure (144 x 30 seconds) over two nights was enough to pick up some of the intricate details of this huge and complex structure. The Western Veil or Witch’s Broom nebula sits to the right of the shot, with the Eastern Veil to the left. The faint triangular patch just visible in the middle is known as Pickering’s Triangle.

Gamma-Cygni-Sadr-regionCutting through the Milky Way, the constellation of Cygnus is home to some of the best sights in the night sky; the North America Nebula, the Dumbell nebula and another one I plan on tackling soon, the Vail nebula.

At the heart of the constellation, bright star Gamma Cygni (Sadr) is surrounded by nebulosity. I first captured this a couple of years ago – a shot which made me realise the potential of a simple DSLR and barn door tracker. I felt it was high time I revisited this old favourite with the 180mm lens.

The butterfly nebula sits to the left of Sadr, with some good structure visible. The intricate bubble-like structure of the crescent nebula can be seen (lower right) amid the vast sea of stars which make up the Milky Way.

perseid-meteor-in-cygnusThis year saw perfect conditions for the annual Perseid meteor shower. With the Moon out of the way, and clear skies for the main event. The aim was to do better than last year, and if possible capture a rare fireball.

I used the super wide angle Tokina 11-16mm f2.8 to give myself the best chance of grabbing the shot.

In the first image, captured a couple of days before the peak, I got lucky with a bright meteor passing through Cygnus. But better was to come with another clear night on the peak of the shower…

perseid-fireballAt around 12:30 am a stunning fireball lit up the sky. A super bright exploding meteor, a bolide, passed directly overhead! Frustratingly I only captured the start of the meteor trail, with the brilliant explosion happening out of frame.

After hastily moving the tripod, I took a sequence of shots of the still glowing ionisation trail left by the meteor, which persisted for several minutes. The animation of 30 second exposures shows the trail dispersing in the upper atmosphere.

Details: Nikon D7000 with Tokina 11-16mm f2.8. 30 second exposures at 11mm, f2.8 and iso 1600.
