Views from today….

Following on from Andy’s earlier post from today (Darwin Walk and Biolam microscope)….

Lichfield Cathedral in the background…

3 hrs in…looking forward to lunch at Mable’s Cafe… Tweedledee and Tweedledumb taking a short break…(I’m not saying which, is which !)

Andy back at ours checking out my cheek cells ! You can see the photos he has just taken through the eye lens still on his phone…

My picture taken with an iPhone6 held up to the 10x eyepiece and 10x objective (plus 1.5x binoviewer).

Solargraph – worked… (sort of)!

Six months has flown by….

Time to collect the solargraph we ‘planted’…

 

Yes, a few days early to be collecting, but today is my last one in the office and I wasn’t thinking of doing a 124 mile round trip to collect from Leominster on the shortest day!

What a lovely start to the day, a slippy stile and muddy walk!

If you remember from the last post, the first attempt had been damaged – probably due to the shiny  ‘foil’ pinhole being pecked out by an interested magpie!

2x previous photos of new solargraph in situ…(Above and below)

The site from Google Maps:

Kimbolton Church (Nr. Leominster) is in the centre. The solar graph is sited in that first tree-line (towards 10/11 o’clock), looking back to the church – thought it would make a nice view/foreground…

This time, we had forgone the foil (you pin-prick it to get a fine hole and therefore sharper image recorded) and instead drilled (No 1 drill bit), straight into the tin. No bird was going to get through that!!

Would this one fair better…?

This was it’s rough view as seen this morning upon collection at 8.45am….

First impressions were good… the baked bean can pinhole camera looked to have survived it’s six months and was in remarkably good condition with hardly any rust – sheltered under the trees.

Back at the office, second impressions were of an unremarkable small image and some image shift (double exposure)…. look how the church is double exposed on the original below….      ;-(

 

I don’t think it was ‘vandalised’ if it had, it would have been ripped out and strewn across the hedgerow… ‘Mother Nature’…. perhaps…? More likely a horse or sheep rubbing up against the stake (or wire fence) – although I did try and protect it somewhat…

(Above: Initial scan – 900DPI, Colour-Millions, mirror reversed on the horizontal plane, cropped).

 

If this hasn’t worked, that’s 18 months from the first try (summer>winter 2016) – I didn’t have another pinhole camera prepared after the first go to put imediately back in place, so waited until this summer solstice in 2017 to try again.

Again, I didn’t have another prepared to start again this morning either, so another camera would have to wait until summer 2018….

 

But….

 

With a little Photoshop magic, it’s amazing what can be achieved!

Phew  😉

So, KIMBOLTON CHURCH SOLARGRAPH Summer > Winter 2017

For January’s RAG end-month meeting, I’ll bring the laptop, scanner, etc. So if you tried your own solargraph and want some help processing it, bring it along and we can have a play!

If you want to preserve yours until then, I suggest you remove from the tin, ***dry completely with a hairdryer*** and then put nice and flat inside an envelope (or two) out of direct light.

Wishing you all a Merry Christmas!

The Joys of RAW…

Never got time this year to build my RAG Aurora talk… it’s nearly a year since we were preparing to head to Alta, Norway….

But work is nearly finished and so I decided to have another play.

This is the jpeg off the camera – way too dark and the aurora far too green – this was a very fast moving teal green, multi-band wave that stretched across the sky. It was far more vibrant and illuminated the scenery…. which is much bigger than it looks here – width wise, this combination captures 114 degrees (84 high, so with the camera angled, the top of the pic is around the Zenith) !

22nd Dec around 6.30pm – I only managed another 10 shots of this outbreak before the battery finally died (that was after eeking out some last shots by warming it up under my armpit!) Thankfully I’d captured the majority of this performance and it was fading out. It was then back to the lodge for dinner, a fast battery re-charge and then headed back out for our final evening….

Tripod mounted, (old) full frame D3 (only 12Mp) and the Nikon 14-24mm f/2.8 lens. Cable release and using mirror lock-up to reduce internal shaking.

800 ISO, 14mm,  f2/8 at only 6 seconds – shows how bright and fast it was moving when you consider what the camera recorded (and the blurring of the bands….) Keeping to 800 ISO keeps dynamic range at the expense of shutter speed. I could have pushed to around 1200-1600 ISO as the cold would have kept the noise down, but that’s how it goes…

6th Dec 2017: NEF RAW file processed in Adobe LightRoom Classic CC (2018) and finished in PS CC 2018. I’ve cropped it down to a more pleasing composition and tried to depict what we saw (although this is more saturated).

The moral of the story is… always shoot RAW!

 

For orientation – the diamond of ‘Delphinus’ can be seen to the lower left just past the tree. Coming out of the top of the same tree is the (Summer) Milky Way, that bright white star just clearing the branches being Deneb in the tail of Cygnus. The bright orange star in the upper left of the photograph is Scheat – if you examine your star atlas, you’ll find it as the top right star in the ‘Square of Pegasus’ !

Plus a short movie, made from 13 files (pre Photoshop) put together in iMovie (the shot above was the third in the sequence)…

Ophelia and Red Sky /Sun 16th October 2017

We were in Sunny Gloucestershire on the 16th when the skies and sun turned red, see first two images.

The state of the car after overnight rain suggested what the culprit was , see image 3, this was confirmed by a lecturer at Nottingham university, see image 4 and checkout this link http://www.bbc.co.uk/news/uk-england-nottinghamshire-41654436

The actual air movement in the atmosphere had been tracked by NOAA, see image 5, the blue track at 2000m shows the movement over the Sahara and on towards UK courtesy of Ophelia( thanks to Stephen Burt of Reading Univ for this ) The final image shows Ophelia over Ireland and the trail of smoke from the fires in Portugal, which may or may not have also contributed to the gloomy atmosphere on Mon 16th.

Rosliston Science Discovery Day 7/10/2017

The sun decided it didn’t want to come out to play this time round….

Despite the wishful thinking of Pete….

I think the ‘special filters’ he was referring to, were unfortunately… CLOUDS!

Instead I had a play with Andy’s new ‘toy’ – a polarising microscope and some purchased pre-prepared ‘rock’ slides, great fun!

Had a go at imaging with the iPhone hand held to the eyepiece. Below a selection of slides at none and fully polarised settings – I think I’ve got the samples in the correct order!

Passed a happy hour or two…

Huddlesford Heritage Gathering 2017

Forgot this was on the phone!

Sunday 24th Sep, J and I took a leisurely walk on the towpath towards Whittington and came across this ‘biennial gathering of Historic Boats’.

What’s that I see….a…

‘Star’ling…  😉

Why a painted urn above you ask..?

Well.. ‘Lisa’ – The Laser Interferometer Space Antenna (LISA) the first space-based gravitational wave observatory of course!

Apart from the fantastic coachwork on display, I’m always on the look out for anything ‘astro themed’, turned up a few!

Like the boat ‘Lyra’!

Link to the site: http://www.lhcrt.org.uk/hhgnews.htm

Here’s Jules… what is the astro link then with this… look carefully…

On the tiller, a beautifully polished brass…

Pegasus!

 

And a Leo theme below…
