The sky at night!

And so after 10 days, I finally had a chance to play with my new telescope on Friday night! Optical astronomy requires at least a few gaps in the clouds but last night at 8pm it was completely clear – I was hopping up and down like an overactive child waiting for the sun to go down (scheduled for about 8:40pm) and simultaneously cursing the slightest wisp of cloud. It should be clear that I’m a bit new to this, so what I write shouldn’t be seen as in the slightest bit authorative.

Kindly folk at @newburyastro had suggested Venus and Saturn as targets for my first adventure into the night. Useful advice because, as a relative beginner I had little idea what I was going to see, or in fact when I was going to see it. Venus become visible at about 9:20pm towards the now-set sun, it turns out that pointing the ‘scope with the finderscope is much easier than the rather more hazardous enterprise of finding the sun without (something I describe here). In the eyepiece Venus appears as a small, bright crescent.

It was a breezy evening which meant that my view jiggled about a bit, it also jiggled about a bit whenever I touched the telescope. However I did manage a picture of Venus taken on my Canon 400D at prime focus. This is an uncropped view, and it’s upside down.

Mars made an appearance a little later at about 9:35pm along with a bright star which I believe is Regulus. This enabled me to get my telescope to work out how it was orientated meaning it could track to objects on demand and also tell me what I was looking at (very handy for a novice). My picture of Mars is a little uninspiring, I’ve zoomed in here as far as possible, in Mars’ favour it does look red and it isn’t a simple point.

By now more and more stars were coming out, so I thought I’d try out my piggyback mount. This image is taken with a 10mm lens (i.e. really wide angle) with the telescope simply used as a camera mount pointed at Polaris, it’s a 30s exposure.

It took a while to get this because I had auto-focus on and the camera couldn’t find anything to focus on so wouldn’t fire – switching off auto-focus and focusing to infinity manually resolved this. It was at this point I wished I could remember how to switch the display on the back of my camera off because it was really bright, and remember which button was which without being able to see it. The thing that surprised me about this is that there are rather more stars than I could see with my naked eye and some of them are quite strongly coloured. I feel I should go about identifying the stars in my picture.

At this point I thought I’d give Saturn a go, I must admit I thought it was hidden behind buildings and trees from my position in the back garden but I punched it into the telescope handset and it pointed me into the side of the conservatory, so I picked up the telescope and moved it one metre to the right, peered through the finderscope and tweaked my direction a bit and… the planet with ears popped into view!! This was really exciting! I only have one eyepiece for my telescope and it’s quite low magnification but through the eyepiece I could see my target was not a point, and it was not round – it was shaped like a flying saucer and there were slight gaps either side of the central body. Having marvelled at this for a bit I thought I’d try for another photograph:

It’s not the best picture of Saturn taken last night but it is my picture!

The moon hadn’t risen before I went to bed, so when I spotted this morning I rushed out for a photo.

The Moon 9(1/500s, ISO400)

 

I’ve not done any astrophotography before these (apart from my shots of the sun, and a couple of shots at the moon through a conventional lens). I guess the thing I carried over from that was that the moon is a rock in full sun, so you need to set your exposure times accordingly, the same is true for Mars and Venus so I suspect I should be using shorter exposure times for them to which will also reduce any motion blur.

My first night of viewing has highlighted a need to have a better grip of how to work your camera, plan what you want to look at in advance and, as with an SLR camera, a telescope is simply a gateway drug for further accessory purchase.

Chester Cathedral

Chester Cathedral from the North

After 7 years living in Chester I have finally gotten around to visiting the cathedral, actually it took a parental visit to get me over the threshold! It was a cold frosty morning in January when we visited.

I am an atheist, but culturally a Christian one, so in a sense I feel at home. I tend to see cathedrals as medieval moon-shots – endeavours of almost unbelievable scale for the time in which they were constructed. We approached the cathedral from the North, along the city walls. Passing along Abbey Street where we saw this rather skewed gateway:

Charles Kingsley, author of “The Water Babies”, was canon at the cathedral and also founder of the Chester Natural Sciences Society. I will spare you the photo of the blue plaque from which I gleaned this information. On the way into the cathedral, the Cloisters.

The Cloisters

You’ll have to forgive me, I’m not too up on the nomenclature for ecclesiastical architectural features, here I am looking down the nave at the altar screen (probably). I’m having problems because of the large variations in light intensity within the scene. There is also some evidence for my problem of always taking photos at a tilt:

Looking East along the nave

A detail in the roof of the nave:

Off the nave is the Consistory Court, this is the Apparitor’s Chair, or maybe it isn’t the information board hedged slightly on this point. The woodwork in the Consistory Court dates from the early 17th century.

Apparitor's Seat

This fabulous device is a Gurney Warm Air Stove, installed in the late 19th century. Sir Goldsworthy Gurney, the inventor of the stove, was an interesting chap.

Chester Cathedral was built in stages, based on a monastic Norman church built in 1093, there are some traces of this original building in the North Transept:

You can’t go to a cathedral without trying to photograph a stained-glass window:

The Choir Stalls, fantastically ornate and clearly difficult to dust:

Frustrated at trying to take photos of difficult to photo things, I thought I’d try something easier: the floor tiles:

That went well, I’ll do some more!

Out into the Cloister gardens where there is this fine sculpture by Stephen Broadbent, from here we could hear the croaking of what sounded like ravens, however the little tinkers remained hidden in the heights of the cathedral tower so it was difficult to be sure:

Stephen Broadbent's Water of Life sculpture

 

I found cathedral photography rather challenging, the problems are that it’s dark and where it isn’t dark it’s very bright! The human eye-brain combination is terribly clever, it seamlessly accounts for enormous variations in brightness without any great degradation in the user experience. As a photographer this all becomes very obvious. There are workarounds: you can provide your own lighting or you can ramp up the sensitivity of your virtual film (increasing the ISO number), use a tripod (if that’s permitted) to allow longer exposure times, and take multiple shots at different exposures melding them into one shot (known as high dynamic range (HDR) imaging).

High dynamic range imaging and display are hot research areas. The problem on the display side is that if you display a picture of a bright window with a dark surround, even an HDR image, then the surround will “look” too dark. What you need to do is vary the brightness of pixels according to their surrounding pixels – it’s called “tone mapping”, precisely what algorithm you should use to do this is the subject of research.

Most of these shots were taken with my new Canon 50mm f/1.4 although a couple were done with the Canon 28-135mm. Next time I think I’ll try out my ultrawide angle lens: 10-22mm, handy for those smaller corners and perhaps a bit less prone to blur.

Going Home

For the half-term holiday, The Inelegant Gardener and I went on a road-trip to visit my parents in the deep south… of England via Malvern where The Inelegant Gardener’s father lives.

The first stop on the tour is Wool, where I grew up. It’s the furthest I’ve ever lived from a motorway: about an hour and a half from the M5 in Somerset. On the way we pass the outskirts of Dorchester where Prince Charles’ model village, Poundbury, is plonked down incongruously on top of hill, it’s pretty pricey. I experience a navigation fail since the bypass is largely new since I left 20 or so years ago and my mental map is slow to update.

Signposts near Wool are decorated with a graphic of a tank (for The Tank Museum) and a monkey (for Monkey World).

The Inelegant Gardener is always amused by the signpost at the edge of the village for “New Buildings”, it’s been there since I was a child. Funnily enough there are new buildings close to the sign in the form of Purbeck Gates, a new development of 160 houses just approaching completion.

Even for a middle-aged atheist like me, it seems the church is the best image of the village, this is the Anglican church where Father Smedley dropped me on my back whilst demonstrating the christening ceremony to the religious education class.

Church of England, Wool

Whilst staying in Wool we went off for a morning in Weymouth, there’s much road building going on since Weymouth will host part of the 2012 Olympics: the sailing part. There is also controversy since upgrading the roads approaching Weymouth will simply dump traffic faster into a small town that can’t handle it, furthermore the council appears to be thinking about charging people to access public land to view the sporting events.

Weymouth Bay

Weymouth has some rather fine Georgian and Regency Buildings.

Fine Georgian buildings on the Esplande, WeymouthIt was an early seaside resort, visited by George III. This is commemorated by a chalk horse on the road out of the town. There is also a statue celebrating his 50th year on the throne.

This is the house where my maternal grandmother started her working life in service at the age of 16, in around 1935:

I’ve always rather liked Weymouth but we rarely visited when I was a child, it turns out this is because my mum went to school in Weymouth and this has put her off the town ever since!

We saw a lot of beach huts on our trip, these are some rather smart examples from Weymouth.

We also visited Lulworth Cove, familiar to many as a geology field trip destination. This is Stair Hole:

I tend to take my home coast for granted, it is now branded “The Jurassic Coast”, and it’s spectacular!

Next stop Southbourne where my dad now lives with my stepmother, this is outside my home territory but not that far away.

Here you can see the lie of the land, with Hengistbury Head directly ahead and the Isle of Wight featuring the “Polar Bear” in the distance to the right.

We went off to Mudeford, where Highcliffe Castle sits on the top of the cliff as you can see – glorious blue skies.

And to finish the trip we went up to the New Forest, Britain’s most recently created National Park. This is a woodland glade close to where dad wants his ashes scattering:

And here’s a mushroom…

There was quite a lot of rainfall during the week!
