The Northamptonshire Natural History Society (NNHS) has been bringing together people with a curiosity about the world around them since 1876. For 150 years, we’ve explored, studied and celebrated Northamptonshire’s natural world, science and heritage.

Today, that same spirit of discovery continues. We’re a friendly community of people with all kinds of interests and experience — from complete beginners to experts — brought together by curiosity and a desire to learn, share and discover.

Our programme covers a remarkable range of subjects, with talks, meetings, practical activities and events throughout the year. You don’t need to know exactly what interests you before you arrive — come along, try something new and see where your curiosity takes you.

Visitors are welcome to attend up to three meetings before deciding whether to join, and when you become a member, you join the whole Society, giving you the freedom to explore all our different areas of interest in our Sections.

Whether you want to learn something new, meet people, get involved or simply explore, you’ll find a warm welcome at NNHS.

One membership. So much to discover!

1896 eclipse in Norway

How Astrophotography has Evolved

Solar Eclipse

Since its founding in 1876, the Northamptonshire Natural History Society has shared in one of astronomy’s most captivating pursuits: the observation of solar eclipses.

In an age before affordable travel and digital imaging, witnessing a total eclipse required determination and careful planning. In 1896, members of the Society undertook a remarkable journey to Norway to observe a total solar eclipse – travelling hundreds of miles in the hope of standing, briefly, in the Moon’s shadow. Expeditions like this reflected the spirit of curiosity and dedication that has long defined the NNHS.

That same spirit continues today. On 12 August 2026, a spectacular total solar eclipse swept across parts of Spain, Iceland and Greenland, while the UK experienced its deepest partial solar eclipse for decades. Across much of Britain, more than 94% of the Sun was covered as the eclipse reached its maximum close to sunset, creating one of the most dramatic astronomical sights visible from the UK in a generation. Many NNHS members travelled to the path of totality, while others gathered across Northamptonshire to witness this remarkable event.

While technology has transformed how we observe and record these events, the sense of wonder remains unchanged. From Victorian expeditions to modern-day observations, solar eclipses connect generations of naturalists and astronomers. They remind us that, however much the world changes, there are still moments when we all look up together in awe.

Astral Projection

Among the photographs taken during the NNHS expedition to Norway for the 1896 solar eclipse is a striking image of the Sun at totality, its disk completely obscured and surrounded by the delicate streamers of the solar corona. To late nineteenth-century observers, such images could appear almost otherworldly.

The radiating structures of the corona – captured imperfectly by early photographic methods – were sometimes described in terms that reflected the wider intellectual interests of the time, including ideas about unseen energies or even “astral” emanations.

Today, these features are understood as part of the Sun’s outer atmosphere, shaped by complex magnetic fields and visible only during total eclipse. Yet the photograph remains a powerful historical record: not only of a scientific observation, but of a moment when the boundaries between careful study and imaginative interpretation were still being explored. In this way, it reflects both the curiosity of the 1896 expedition and the enduring sense of wonder that continues to inspire NNHS members today.

Deep Space

Northamptonshire Natural History Society brings together highly knowledgeable and experienced amateur astronomers with a shared passion for exploring the deep sky universe beyond our Solar System. From distant galaxies and nebulae to star clusters and variable stars, members use their own telescopes and equipment alongside a wealth of practical experience to study the night sky in detail.

Knowledge is always shared freely within the Astronomy group – whether discussing observations, offering advice on equipment and techniques, or helping others discover what to look for. The section combines expertise with a welcoming, collaborative spirit, making it an ideal place to deepen your understanding of astronomy while learning from dedicated observers who continue the Society’s long tradition of serious amateur study.

Clouds at Night

Noctilucent clouds, often called “night-shining clouds,” are one of the most magical sights you can catch in the sky. Unlike ordinary clouds, they form incredibly high above Earth—so high that even after the Sun has set for us, they can still be lit up from below the horizon. This gives them a glowing, electric blue or silvery appearance that almost looks unreal. They’re most often seen during summer evenings near the horizon, especially in northern regions. If you ever spot thin, shimmering clouds lighting up the twilight sky, you might be looking at one of the rarest and most beautiful cloud types on Earth.
