I’m a SQL analyst and developer by profession, living in Dorset, United Kingdom, which is an amazing place for people who love outdoor activities. I love mountain biking which has taken me to stunning locations, and there are miles of breath-taking walks with lots of nature and history around – every corner has a surprise, it’s like living in a fantasy, at least that’s how I see it.

Since I was a child, I’ve always had a fascination for the stars. I had the opportunity to visit places near the equator with true dark skies, where the Milky Way core is visible up in the sky – unlike in the UK where the core is barely visible on the horizon. It’s of unbelievable beauty. I spent most of my childhood visiting locations in the rain forest, flat lands and my favourite – the mountains, especially over 4000 meters.

My fascination for the night sky has always been with me and I have always wanted to capture their beauty. One day, I saw images from Michael Shainblum and he then became my main influence and inspiration. I’ve never looked to replicate his style or the others, it was just that I loved how his images made me feel so immersed. It inspired me to do the same with my photos, to capture an image that would put the viewer under the stars.

As I did last year, I went again to the same place for my first Milky Way, Peveril Point, Swanage, Dorset UK. For my previous attempt, I used a Sigma Art lens 20mm F1.4. The idea was to capture more detailed foregrounds. The lens proved to be excellent for low light but it has four major downsides: first, photos of the night sky taken with this lens were extremely difficult to edit. Second, it is not very good for panoramas, despite I used a nodal head. Third, the autofocus is the worst of any lens that I have ever owned, it is very difficult to capture a sharp photo even with the best light conditions. And fourth, the lens profile in Lightroom is terrible, it makes the images worse. I was not bothered by the astigmatism distortion of the corners which virtually disappeared in panoramas. Overall, I was not happy with the lens, I felt I wasted my last year trying to use it. So I went back to my trustworthy Samyang lens 14mm F2,8. Coupled with the Canon 6D, still my preferred choice. I have not tested the Sigma 14mm F2 yet, but given the price, I will stick with my Samyang.

The image to the rights is the process used to create it. It is a panorama of 7 photos, Canon 6d and Samyang 14mm F2.8, ISO between 4000 and 5000. Each photo is 25 secs. Stitched in Adobe Lightroom.

The moon rise was spectacular, one of the most beautiful rises from the sea, it was also so dim that allowed to capture the Milky Way up to the last minute before the astronomical dawn. Again, I thank you the nature for this beautiful experience.

All images have been captured with a Canon 6D Mk1. And most of the images were captured with a Samyang 14mm F2.8 Lens, my more recent work is being captured with the amazing Samyang 14mm F2.4 XP

Durdle Door, Dorset.

Durdle Door, Dorset.

Image by jasty78

Durdle Door (sometimes written Durdle Dor) is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England.

It is privately owned by the Welds, a family who owns 12,000 acres (50 km2) in Dorset in the name of the Lulworth Estate. It is open to the public. The name Durdle is derived from the Old English word ‘thirl' meaning bore or drill.

The form of the coastline around Durdle Door is controlled by its geology—both by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds. The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. The rock strata are almost vertical, and the bands of rock are quite narrow. Originally a band of resistant Portland limestone ran along the shore, the same band that appears one mile along the coast forming the narrow entrance to Lulworth Cove. Behind this is a 120-metre (390 ft) band of weaker, easily eroded rocks, and behind this is a stronger and much thicker band of chalk, which forms the Purbeck Hills. These steeply dipping rocks are part of the Lulworth crumple, itself part of the broader Purbeck Monocline, produced by the building of the Alps during the mid-Cenozoic.

The limestone and chalk are in closer proximity at Durdle Door than at Swanage, 10 miles (16 km) to the east, where the distance is over 2 miles (3 km). Around this part of the coast nearly all of the limestone has been removed by sea erosion, whilst the remainder forms the small headland which includes the arch. Erosion at the western end of the limestone band has resulted in the arch formation.

UNESCO teams monitor the condition of both the arch and adjacent beach.

The 120-metre (390 ft) isthmus which joins the limestone to the chalk is made of a 50-metre (160 ft) band of Portland limestone, a narrow and compressed band of Cretaceous Wealden clays and sands, and then narrow bands of greensand and sandstone.

In Man O' War Bay, the small bay immediately east of Durdle Door, the band of Portland and Purbeck limestone has not been entirely eroded away, and is visible above the waves as Man O'War Rocks. Similarly, offshore to the west, the eroded limestone outcrop forms a line of small rocky islets called (from east to west) The Bull, The Blind Cow, The Cow, and The Calf.

As the coastline in this area is generally an eroding landscape, the cliffs are subject to occasional rockfalls and landslides; a particularly large slide occurred just to the east of Durdle Door in April 2013, resulting in destruction of part of the South West Coast Path.

There is a dearth of early written records about the arch, though it has kept a name given to it probably over a thousand years ago. In the late eighteenth century there is a description of the "magnificent arch of Durdle-rock Door", and early nineteenth-century maps called it 'Duddledoor' and 'Durdle' or 'Dudde Door'. In 1811 the first Ordnance Survey map of the area named it as 'Dirdale Door'. 'Durdle' is derived from the Old English 'thirl', meaning to pierce, bore or drill which in turn derives from 'thyrel', meaning hole. Similar names in the region include Durlston Bay and Durlston Head further east, where a oastal stack suggests the existence of an earlier arch, and the Thurlestone, an arched rock in the neighbouring county of Devon to the west. The 'Door' part of the name probably maintains its modern meaning, referring to the arched shape of the rock; in the late nineteenth century there is reference to it being called the "Barn-door", and is described as being "sufficiently high for a good-sized sailing boat to pass through it."

Music videos have been filmed at Durdle Door, including parts of Tears for Fears' "Shout", Billy Ocean's "Loverboy", and Cliff Richard's "Saviour's Day"

The landscape around Durdle Door has been used in scenes in several films, including Wilde (1997) starring Stephen Fry, Nanny McPhee starring Emma Thompson,

the 1967 production of Far From The Madding Crowd (the latter also filmed around nearby Scratchy Bottom), and the Bollywood film Housefull 3.

Ron Dawson's children's story Scary Bones meets the Dinosaurs of the Jurassic Coast creates a myth of how Durdle Door came to be, as an 'undiscovered' dinosaur called Durdle Doorus is magically transformed into rock.

Dorset-born Arthur Moule, a friend of Thomas Hardy and missionary to China, wrote these lines about Durdle Door for his 1879 book of poetry Songs of heaven and home, written in a foreign land:

Good Lighting Advice

Digital photo magazine

by Chasing Stars

To achieve International Dark Sky Reserve status all those responsible for lighting (local authorities, highway departments, businesses and individual residents) are required to ensure that light pollution (light escaping sideways and upwards) is reduced to a minimum.

LEDs are now beginning to appear above our streets and main roads in very large numbers. Sadly, far too many LEDs are very bright, and their excess light reflects from the ground into the sky.

AONB Position Statement & Good Practice Note

The AONB position statements set out its current position on a variety of topics. These include light pollution, and the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty derives much of its beauty from its qualities of tranquillity, remoteness and cultural heritage. Light pollution has the potential to erode and destroy that tranquillity and sense of remoteness.

It is, therefore, considered appropriate that all artificial external lighting within its borders, or within the setting of the AONB, should be muted, screened, and the minimum required.  

Position Statement 1 - Light Pollution (PDF, 75Kb)

Good Practice Note 7 - Good External Lighting (PDF 70Kb)

Position Statement 7a - Recommendations for Dark-Sky compliant lighting on new builds & refurbishments - a Developers' Guide (PDF 500kb)

Terms used in describing good lighting, and waste light not directed to the area to be lit.


Task or Useful light – light that fulfils the task for which the lamp was installed.

  • Obtrusive light – light causing a problem of some kind through misdirection.

  • Spill light - falls outside the area where it is needed.

  • Upward reflected light - unwanted light bouncing off the ground.

  • Direct upward light - wasted light shining above a light fitting (not necessarily vertically upwards – it may be escaping just one degree above the horizontal but will eventually end up in the sky).

  • Light intrusion – over-bright and poorly directed light, often going in windows and/or causing glare and discomfort on other premises. Sometimes called light trespass, but this term is normally to be avoided as, in law, trespass is deliberate intrusion and the intrusive light is usually the result of ignorance rather than malice.



Compact LED light directed downwards. This and similar types are recommended for domestic, commercial, farmyard and similar uses: preferably with sensors to switch off when not needed.

Environmental Zones

It is recommended that Local Planning Authorities specify the following environmental zones for exterior lighting control within their Development Plans.

ZoneSurroundingLighting EnvironmentExamplesE0ProtectedDarkUNESCO Starlight Reserves, IDA Dark Sky ParksE1NaturalIntrinsically darkNational Parks, Areas of Outstanding Natural Beauty etcE2RuralLow district brightnessVillage or relatively dark outer suburban locationsE3SuburbanMedium district brightnessSmall town centres or suburban locationsE4UrbanHigh district brightnessTown/city centres with high levels of night-time activitySource: Guidance Notes for the Reduction of Obtrusive Light GN01:2011

Where an area to be lit lies on the boundary of two zones the obtrusive light limitation values used should be those applicable to the most rigorous zone.
NB: Zone E0 must always be surrounded by an E1 Zone.

1.       King Alfred’s Tower

Kingsettle Hill, South Brewham, Bruton, Somerset BA10 0LB

King Alfred’s Tower is a striking 160ft (49m) folly, built in 1772 for Henry Hoare II, known as Henry the Magnificent, the designer of the iconic  Stourhead gardens. It is believed to mark the site where King Alfred the Great rallied his troops in 878. The tower commemorates the accession of George III to the throne in 1760 and the end of the Seven Years War. Henry would surely have appreciated the majesty of the night sky as much as his own creations and this site provides a perfect spot from which to admire the beauty above.

6.       Knowlton

Knowlton, Wimborne, Dorset BH21 5AE

Many people report a strange sensation when standing at the centre of Church Henge, among the ruins of the medieval church. This is perhaps because it is at the heart of a major pagan ceremonial site, once taken over by Christian worship, but now returned to nature. Surrounding the site is the largest concentration of pre-historic barrows and henges found anywhere in the UK. Read up on the constellation myths created by our ancestors that tell of gods and monsters, heroes and villains and other legends using only the stars in the night sky and then witness the incredible theatrical display for yourself. The backdrop of the stunning church also makes for fantastic astrophotography.

Light Pollution

The Good and the Bad

The Good and the Bad


Why do our dark skies need protecting?

The night sky makes up half of our visual environment and yet, unlike historic housing, ancient settlements, resident wildlife and our fantastic landscapes, the night sky has no protection, which explains why in just six years light pollution has increased by 24%.

This is not just bad news for people who can no longer be enthralled by the night sky. The amount of money squandered by ‘wasted’ light is staggering, plus the cost to human and wildlife health is significant. Making just a small low-cost difference to our lighting could bring about massive changes for the better.

Pollution is just that – light that is wasted and not used to light the things that people need. We all need light and certainly don’t want to make the AONB a light-free zone. All we want to do is ensure that we have the right lights in the right place at the right time.

The impacts of light pollution are significant, but small changes can make a big difference.

Is light pollution really that bad?

Even though it doesn’t smell bad, and if you’re used to it, it doesn’t look that bad, light pollution has been proved by experts to be just as bad as air and environmental pollution – it’s just not as obvious.

Here are some facts to get you started….

  • Total of 830,000 tonnes of CO2 pollution is produced from the energy wasted by streetlights alone.

  • The estimated cost of wasted light (that which isn’t shining on the things we need to illuminate) is a staggering £1 billion.

  • Light pollution is directly linked to a decrease in robin, songbird and owl populations.

  • Insects are the basis of many food chains, but one street light can kill up to 150 each night.

  • Lighting at night disrupts our circadian rhythm which has been proved to increase your risk of stress by 52%. It is linked to more serious health issues too.

Let’s look at this more positively…

  • There is increasing interest, wonder and amazement at the incredible array of stars above us. Stargazing is a fabulous educational activity for all and by keeping our dark skies you’ll be one of the lucky 10% of people in this country to enjoy this spectacular show.

  • Dark skies make the Cranborne Chase AONB unique, encouraging people to visit from polluted areas to escape to our pocket of tranquillity. That means more income for businesses through people arriving and staying longer.

  • Saving money. Substantial savings can be made by local authorities, businesses and individuals by turning off or dimming down unnecessary lighting. That means more money for the things that matter.

  • Saving energy. There is no point shining a light into the sky. Energy wastage can easily be considerably reduced – which is so much better for the environment.

All of the above is wasted light.

Easy ways to protect and enhance our dark skies… and banish the pollution

It is often said that if we all do a little, collectively we can make a big impact. In one small area of Wales, angling lights to illuminate the ground and turning off lights when they were not needed reduced light pollution by 10%.

Do you have concerns about street lighting or obtrusive lighting from another property? Let us know. We will not divulge your details but will work with others to install lighting which is a win win for everyone.

If you are interested in finding out more about light pollution, its impacts and some solutions, visit the websites below, both of which have some great resources on this subject:

Outstanding Dark Night Skies

Cranborne Chase can celebrate the fact that more than 50% of the 380 square miles of the AONB still has the lowest levels of light pollution in England - and the rest of the Chase is not far behind.

In fact, the Chase is one of the best places to stargaze in England. Our aim is to help you enjoy this aspect of our AONB as much as our multitude of other ground-based treasures. The great thing is that whether you work, live or visit the Cranborne Chase AONB there is something to see 24 hours a day.

There are currently only two other. areas in England that have been formally recognised for their low levels of light namely Exmoor Dark Sky Reserve and Northumberland Dark Sky Park. With your help Cranborne Chase AONB could be the third.

This important designation will not only put us on the map, but allow us to protect and enhance our night sky for generations to come.

How can you help?

Visit Survey monkey to sign our pledge. We would love your support. Please sign our pledge to show your love for our dark skies and our bid to get them protected. We would also love to know what you think of your own local dark skies. Please send us your photos, poems and stargazing adventures.

Do you have an iPhone? We are looking for volunteers to help us take measurements of the night sky. No experience is necessary and it’s as easy as downloading an app, standing outside and pressing a button – and hey presto and we have another piece of evidence to show how amazing our skies are.

DIY SOS (save our skies)

Why not give your home a low cost dark sky makeover? You would be amazed how easy it can be to make a few small changes that will transform your night view.

Here is an easy guide, but if you need help just let us know. Once you have done it please tell us – it all helps towards gaining Dark Sky Reserve status.

We are looking for volunteers too to work with us to show the accreditors we are serious about protecting our dark skies. Could you help by working with us to reduce light pollution in your community or business? We promise lots of publicity, plus plenty of support along the way.
