Star Stories Photography and Aurora Special


The aurora over Ceannabeinne Beach on the north coast by photographer Graham Bradshaw

Despite the stormy conditions earlier in the evening, skies cleared up beautifully at Abriachan on Saturday night for Star Stories.

Graham Bradshaw of Graham Bradshaw Photography was our guest speaker, talking about his fascinating experiences hunting and photographing aurora in some of the wildest and remotest parts of the Scottish highlands.  His talk included practical advice on seeking out aurora in the north of Scotland (which is much more prevalent than you might think), as well as showing many beautiful still images and stunning time lapses captured all over the highlands and further afield.

Meanwhile I took two groups out stargazing and managed about 20 minutes of clear skies during the first outing until we were rained off by a very brief shower.  After heading back inside I switched to my backup slide deck on the science of aurora, talking about how the differential rotation of stars causes kinks in their magnetic fields, ultimately leading to the coronal mass ejections that produce the aurora.

I got a nice capture of the Andromeda galaxy over the forest classroom (left), and a passing satellite.  This giant galaxy is over 2.5 million lights years away just visible naked eye.  It looks even more impressive in binoculars.

By the time Graham had finished his first talk, skies had cleared again and my second group had a much longer excursion under the stars.

As usual we took in broad sweeps of the night sky with the wonderful agility of binocular observing, hitting targets like the Orion nebula, Hyades and Pleiades star clusters, the Andromeda galaxy, Beehive cluster as well as numerous bright and massive red and blue giant stars.  The Milky Way was also clearly on display, even with the presence of an enchanting crescent Moon hanging in the South West.  We also saw Mars sitting above the Moon and had a go at finding Uranus (currently observable in the same binocular field as Mars).

During both streams Suzann Barr did some video interviews with some of the younger stargazers who’ve become regulars at the events, and captured feedback on our Star Stories wall chart.  Overall it was another great evening with good feedback from participants.

Our next event in March will be the last dark sky observing session for this season as skies begin to brighten.  The theme for this event will be galaxies, and I’ll have a backup presentation prepared on this topic should skies prove unfavourable.  There’s only a few tickets left available on Eventbrite here.

Another good catch in my camera, this time the Milky Way in the region of Perseus, with the double cluster clearly visible on the left.



The Perseids 2018


The period between August 11th -13th will mark peak activity for the annual Perseid meteor shower.  Like all annual meteor showers the Perseids occurs due to the Earth ploughing through the fine debris left behind by a short period comet, in this case Comet Swift-Tuttle.  Rates of shooting stars could be as high as 60-70 per hour at peak although this figure is under the most favourable of conditions and you’ll likely see less.

This year’s Perseids looks set to be the best shower of the year due to favourable Moon conditions.  A thin crescent Moon will set before the shower gets properly underway providing excellent sky conditions if you’re sufficiently away from urban lighting and (of course) have clear skies.

Even if you don’t see any shooting stars you can always look out for Saturn and Mars in the south, both setting between 2 – 4am in the morning, and appreciate the increasing number of stars popping into view as our subarctic skies gradually darken.

The radiant for the shower is within the constellation Perseus the hero, although you don’t need to look in this direction to see them.  In fact some of the longest fireballs and streaks caught on camera will be picked up looking away from the radiant.

Due to the brightness of skies this far north you’ll want to wait for the Sun to dip as far below the horizon as possible to achieve the most favourable darkness, this means you’ll want to observe as late as possible, ideally close to or after midnight if you can.

Shooting stars and meteor showers are one and the same phenomena – fine lumps of material impacting the earth’s atmosphere about 40-60 miles overhead.  These tiny pieces of debris are travelling so fast they superheat when entering the atmosphere and burn up rapidly.  Occasionally a larger piece will impact resembling a spectacular fireball.

Remember, you don’t have to look directly at the radiant to see a meteor shower, this is just the area of space they’ll originate from.

Observing Meteor Showers

You don’t need any special equipment to view a meteor shower, in fact binoculars or telescopes will just narrow your field of view. Grab a deck chair or a warm blanket, prepare a hot drink, wrap up warm and lay out under the darkest conditions you can find. It’s an excellent activity to do alone or if you have children they’ll love an excuse to get outside for some after dark play.

Put away any lights or bright mobile phones and simply look up and wait. Remember it takes up to 30 minutes for your eyes to fully dark adapt and any exposure to bright lights will start the process all over again. If you need a light red touches are best for preserving your night vision.

Clear skies!
