A basic pair of 8x40mm binoculars lets you access around 500,000 stars

Many people think astronomy is a complicated or technical activity. While it can be, it very definitely doesn’t need to be. Over 90% of my observing is done with a simple pair of binoculars, like these light and inexpensive 8x40s, which I try to carry with me wherever I go on local walks or further afield.

With these I can access stunning images of the Moon, resolve the satellites of Jupiter, sweep through over 500,000 stars (most too dim to see naked eye), resolve glittering star clusters like the Pleiades and Hyades, and (under suitably dark skies) view the dim light from galaxies many millions of light years away.

Marry the binoculars with a small tripod and a night sky app on your phone and you have everything your need for agile observing during clear skies or brief opportune breaks in the weather.

Clear skies.

Destination Mars

I’m very happy to be partnering with Skills Development Scotland and the Science Skills Academy to deliver day 2 of the ‘Destination Mars’ three day programme for S1 and S2 pupils in Thurso’s recently built Newton Room (22nd – 24th July).

On day 2 I’ll be exploring Mars impact geology, the solar system, night sky tours and a workshop on optics and spectroscopy.

Solstice Sunsets

The sunsets in the Highlands of Scotland are some of the best in the world when conditions are right, especially around the solstice when the setting Sun grazes just 8 degree below the northern horizon producing mesmerising night long sky glow.

On June 22nd I camped out at the Bunchrew shoreline with my daughter Violet and managed to capture some video and still images of the sunset looking north towards Ben Wyvis.  Footage captured around 10.45pm.

Star Stories – Solstice at the Shielings

Solstice celebrations up at Abriachan tonight. We had a nature walk and talk up to the Shieling above Loch Ness, with Suzann, Christine and Clelland imparting plant and flower lore at various points up the trail.  From the top we learnt all about Shieling life, dairying and got to sample some simple crofting fare.

I then presented a short talk on the Solstice and its astronomical significance, culminating in a human henge to illustrate the changing seasons, rising and setting Sun points and how the ancient Celtic people marked off their Wheel of Time.

We just managed to catch a lovely sunset from the top of the hill before making the trek back down.

The Star Stories events will be resuming in October with another event in collaboration with the Highland Archaeology Festival.  Look out for programme details as they emerge.

Happy Summer Solstice

Happy Solstice! Official time off the solstice today is at 3.54pm GMT when the north pole of the earth is maximally inclined towards the Sun.

In the north of Scotland we currently experience over 18 hours of daylight and no true night at all, as the Sun dips a mere -8 degrees below the horizon at its lowest point at 1.20am.

Official sunset time today is 22.20pm when the Sun will be at its greatest setting extremity towards the North.  This is where the term Solstice comes from, Sol -Sistere, or Sun Standstill.  The point when the Sun reaches its maximum declination in the sky or its furthest rising and setting points north of east and west on the horizon.

The situation is reversed for out friends in the Southern hemisphere of the planet who are currently marking the winter solstice.

Clear skies if you head out to take in the setting Sun!

Come and join us for an outdoor walk and talk to the Sheilings above Loch Ness. Learn about summer plant lore and old dairying activities from Abriachan’s Suzann and Christine as we walk up the hill.

Once we reach the Shieling local astronomer Stephen Mackintosh will give a talk on ancient astronomy and how many cultures would mark the solstices in days gone by.

Some traditional refreshments will be available at the top after the walk (30 mins uphill).

Meet: Friday 21st June after the Abriachan Highland Games at 8.30pm.

Park at the fank carpark NH559348. For detailed directions please advance email abriachanforest@gmail.com or call 01463 861236. All ages welcome.

Tickets available via Eventbrite.

Due to the outdoor nature of this event it may be cancelled due to very poor weather. Please check the ‘Abriachan Community ‘or ‘Highland Astronomy’ Facebook pages for details on the day. This event is part of the Star Stories Astronomy and Storytelling programme, part funded by the STFC (Science and Technology Facilities Council).
