A human henge – mid summer at Abriachan
Some good news regarding future face to face astronomy programs, delivered up in the Scottish Highlands. All of this is caveated on the assumption that live gatherings are legal and safe at the end of this year.
Next season (from November) I’ll be continuing to work with Caroline Snow to deliver our Urban Astronomy programme based out of the Friends Of Merkinch Local Nature Reserve in Inverness (with the Sea Scouts hall as our indoor base of operations). These events have been growing in popularity and we’re really glad they’re going to continue.
Merkinch Moon gazing
Star Stories will also continue from Abriachan Forest (Dark Sky Discovery Site) with Suzann, Clelland, Ronnie and the rest of Abriachan Communityteam. The STFC spark award funding is due to end this season, but the programme will continue on a sustainable footing with events (hopefully) starting in November. This whole programme has been a massive success and I look forward to completing my research report for STFC with dissemination for various astronomy publications.
Clelland in action
I’ll also continue my hotel based outreach work for the likes of The Torridon and appearances at various festivals, whenever it’s safe and practical to do so.
Some future plans are also underway, including an outreach programme with much bigger scope that will involve various partners and potentially some innovative new technology.
Stage all set for my stargazing show Belladrum Tartan Heart Festival. On both evenings sky conditions were good enough for the show to move outdoors under clearing skies,
The stars were out at Belladrum Tartan Heart Festival last weekend. Not those on stage, but the more distant and ancient ones up in the sky. I had loads of fun sky guiding outdoors with all the late night merrymaking around us – a markedly different experience to the stillness of SCAPA festival but none the worse for it. My portable PA came to the rescue and managed to win out against one of the louder music tents across the way and questions and answers were easily fielded.
On both evenings skies started cloudy but partially cleared by about 11.30pm, allowing me to take the show outside for a laser pointer assisted tour of the heavens.
Skies to the north were sufficiently clear to tour the rich pickings around Ursa Major, with its famous double star Mizar and its abundance of celestial pointers, leading to Polaris and many of the other bright stars in the sky
Amidst opening and closing patches of sky we saw red giant Arcturus, Vega, distant Deneb, the stars of Ursa Major, Cassiopeia (both pictured), Cygnus, Lyra and Aquila.
With binoculars folk were able to easily split some well known double stars including Mizar and Alcor in the handle of the dipper and the Double Double next to brilliant Vega.
The highlight, close to midnight, was viewing the Andromeda galaxy, which was just visible despite the very challenging conditions. A few people had never seen another galaxy before and amazed binoculars could produce such excellent views.
Thanks to everyone who came along, a safe homeward journey and clear skies! I look forward to returning next year.
The milky way from the grounds of the Arkinglas Estate, Loch Fyne
I had another great time hosting outdoor astronomy and stargazing workshops at this years Scapa festival, held on 3-5th May near the shores of Loch Fyne at the Arkinglas Estate.
It was very busy, especially Friday evening when clear skies brought many folk streaming down into the gardens in anticipation of stargazing close to the shoreline.
As it happened we hit some cloud just as I was about to kick off, prompting a quick jump over to my backup projector and screen. I was then able to deliver a 30 minute talk with Q&A, discussing things like the colour, temperature, distance of stars, the Milky Way, other galaxies, shooting stars and large impactors. As ever the questions were fascinating.
A passing satellite
Just as the talk wrapped up skies cleared and we were stargazing from the estate grounds. Plenty of constellations and bright stars began appearing, and conditions improved further when a second group arrived to join in.
Similar conditions prevailed on the Saturday, when skies once again cleared up after my talk, allowing us to observe with the large case of binoculars I always bring to star parties.
Later on I was able to photograph some lovely shots of the Milky Way from the estate grounds, with the band of our galaxy sitting low and clear on the northern horizon.
Feedback has been great on the guiding so far, and I’m looking forward to getting involved again next year.
Starry skies over the Moray coast
Amidst a very busy schedule last month I managed to head out to Roseisle (along the Moray coast) for some observing and a wild camp. My original mission was to try and catch a geomagnetic storm predicted by the MET office space weather forecasts. As it happened the promised aurora didn’t arrive but I did manage to get some photos of the starry skies that opened up on Saturday night, starting with the International Space Station.
Not the most fantastic ISS shot but I only had about 20 seconds to set up after running down the dunes to capture the pass!. The station is actually travelling from west to east here, towards Sirius (bright star on left)
From there I took a number of pictures hoping to capture some aurora, but instead imaging the crisp starry skies. I’ll let the photos do the talking from here – please read the caption notes.
This image of the Plough (minus Alkaid) was snapped while I was still under the trees, on my approach to the beach. You can clearly see the naked eye double star Mizar-Alcor at the bottom of the image. The main stars in the Plough are roughly 100 lights years away. Our Sun would not be visible naked eye if placed this far away which tells us something about the scale and luminosity of these titan stars.
Looking north towards Burghead where I hoped to capture some aurora. Instead I picked up the rich star fields within the Milky Way near Cassiopeia.
One of many passing satellites.
An interesting shot looking north west. The bright white light is the Portmahomack lighthouse and the orange light pollution on the right is likely from Helmsdale. Perhaps the most interesting feature in this photo is the faint smudge of light in the top left. That’s the Andromeda galaxy – a separate spiral galaxy (larger than our Milky Way) over 2.5 million light years away.
The formation of a young protostar following the collapse of a previously inert dust cloud
We had a great turnout for March’s Urban Astronomy session last week at the Sea Cadet’s Hall in Inverness. The indoor presentation massively benefited from our new giant screen, expertly erected by Robbie (pictured below). Here’s a selection of slides from my presentation on naked eye observing and the life of giant stars.
Robbie putting the final touches to our new giant screen for indoor astronomy presentations and virtual sky guiding
– Naked eye and binocular observing
– Satellites: Iridium Flares and ISS
– Colour, temperature and mass of stars
– The Hertzsprung-Russell diagram
– Protostar formation from dark nebulae
– Main sequence burning and final fate of stars
– White dwarfs, supernovae, neutron stars and black holes.
As ever there were some superb questions during and after the talk. Stay tuned for upcoming events as myself and Caroline roll out the program.
In the simplest terms stars behave like black body radiators with colour linked to their surface temperatures.
The brightest stars in the night sky can be close – like Sirius – or giant stars very far away (eg. Betelgeuse, Rigel, Deneb).
The HR diagram. An elegant and reliable tool for describing the evolution of stars from main sequence burning into their final stages of life
Another video guide – this time centred on the constellation Leo, the guardian of Spring skies in the northern hemisphere. Did you know about the beautiful double star in the Sickle called Algieba? Or the dwarf galaxy visible next to Regulus under the darkest skies?
With special thank to Random Records and artist Kanc Cover for the background music.

I’m looking forward to presenting another astronomy talk for the 2019 Inverness Science Festival. Talk details below:
Astronomer Stephen Mackintosh from Highland Astronomy will take you on a journey through space and time, looking at the massive stellar structures that make up the observable universe – Galaxies.
How did we discover them, how many are there and what do they tell us about the immense scale and dynamics of the universe?
Plus tips and advice on observing galaxies and other faint deep sky objects for yourself.
Time: 7pm – 8pm, 8th May 2019
Venue: Main Lecture Theatre, UHI Campus
