Another stunning Milky Way shot by Christopher Cogan taken from Muie in Sutherland in the far north of Scotland.

Two stunning Milky Way images taken last night from the Scottish Highlands (and Islands). Both show the bright region of the Milky Way in the vicinity of the Summer Triangle, looking south.

If you imagine our Milky Way as a vast disk of stars, these views are peering further ‘into’ the disk, where the density of stars and stellar matter is greater, and hence brighter. Contrast this with the fainter regions we see in Winter near Orion, when we peer ‘out’ of the galactic disk.

The dark lanes you can see are part of the Cygnus Rift – a region containing vast clouds of dust that obscure some of the light from the billions of stars in the background.

With the Moon well out of the way and proper darkness returning late at night, now is a great time to go out and see the Milky Way for yourself.

Observing the Moon

Here’s a video (with some voice over) I shot last night when out Moon gazing from my back garden.

I never ever regret the tiny effort and time investment involved in digging out my binoculars or telescope to have a look at the Moon.

Clear skies.

Star Stories Astrophotography Special

Eric presenting his guest talk up at Abriachan

There were only a few stars up at Abriachan Forest tonight for our Star Stories Astrophotography special, but some nice early views of the waxing crescent Moon and Venus before the weather really turned and a mini snowstorm descended.

Many thanks to our guest speaker Eric Walker from the Highlands Astronomical Society for delivering a fantastic talk on astrophotography.  Eric showcased a ton of amazing images he’s taken over the years demonstrating his passion for astronomy and observing.

Clelland also entertained in the round house with storytelling and we had a nice impromptu discussion about the night sky over the campfire between changeovers.

The next Star Stories is our Vernal Equinox special in March, which will be the last opportunity for dark sky observing this season before the return of longer days.

Dark Skies at Torridon

The Milky Way over the grounds of the Torridon Resort

I’ve had some fantastic excursions out to the Torridon Resort recently, where I deliver outreach astronomy and stargazing for guests at the hotel.

Weather can be unpredictable this far west but when conditions open up the skies are undoubtably some of the darkest in Scotland, easily surpassing the darkness levels over the Cairngorms, which are still hindered by skyglow from the populated Moray coast.  This far west there’s almost no skyglow and inky black skies allow amazing views of the Milky Way and deep sky objects like the Andromeda galaxy, open star clusters and faint nebulae.

In addition to hosting several stargazing dinners I was also involved in some filming with the BBC up at the Torridon and look forward to seeing if the starry sky sequences make the final cut.

If you’d like to treat yourself or a loved one to a special stargazing experience please see the details here on the Torridon’s website.  Meanwhile, enjoy some recent pictures I took from the hotel grounds and nearby Achnasheen.

Hebridean Dark Sky Festival

I’ll be touring the outer Hebrides delivering outdoor stargazing as part of the Hebridean Dark Sky Festival 2020. The festival is a fantastic reason to visit the isles during the winter months and appreciate their world class dark skies.  Organisers An Lanntair  have put a fantastic programme together spanning music, art, theatre and stargazing.

Details of my own route and outreach locations for stargazing will be published soon so stay tuned.  For full festival details and some early booking links please visit the festival website.

The Northern Lights

The northern lights looking over the Beauly firth towards the Black Isle, Inverness-shire

After reports of a KP6 geomagnetic storm predicted to strike Scotland over the weekend, and clear skies on Sunday evening, I headed out after sunset to try and catch the northern lights.  This was a very early aurora excursion as nights have only just got dark enough for decent views of the night sky, let alone tracking down the faint and elusive northern lights.

My initial outing took my into the hills above Bunchrew where I bagged some lovely views of the summer Milky Way overhead.  Turning my attention north I noticed a faint arc of light on the horizon,  and sure enough some test shots picked up a vibrant band of purple and green auroral light.  However little structure was evident until I moved to lower elevations, reaching the Bunchrew shoreline just after 10.30pm.

From this new vantage, in the dark looking over the Beauly Firth,  the northern lights stood out much more clearly as distant columns of white light, slowly morphing and scintillating above the horizon.  Some of the images (attached) show nice structure and the suggestion of wave like movement.

As our nights get darker many more opportunities to view the aurora will present themselves.  The best strategy is to simply get out there as often as you can when it’s clear, and try and escape the boundaries of light polluted towns and cities.  Aurora forecasts should only be used as a guide as they’re seldom reliable.  Remember to look north and where possible find some nice low horizons in this direction.

Good luck and clear skies.

The aurora is caused by the solar wind slamming into the earth’s atmosphere near the poles, ionising chemical elements which produce light at very specific quantised frequencies.

 

 

The Summer Milky Way

Late summer is prime time for observing the Milky Way, and esp. catching the bright core visible near the southern horizon after dark. This bright area marks the central nucleus of our galaxy, some 30,000 light years away..

The Milky Way currently runs between Saturn and Jupiter, both low on the southern horizon, and intersects the three bright stars of the Summer Triangle asterism (Vega, Deneb and Altair). From south It runs overhead and terminates close to the constellation Perseus in the north East.

For the best views you’ll want to get away from urban light pollution, ideally somewhere fairly rural. Let your eyes dark adapt for at least 15 minutes to give yourself the best possible views.

Clear skies.
