mini-WASP update

I have a new all-Aluminium connector designed and built for connecting an SXM26C (or H18 mono) CCD at the correct metal-back distance to the focal reducer on the Sky 90 refractor.  I am just getting a further 3 of these custom-built connectors made so I have one for each of the 4 x Sky 90 scopes.  Each connector has an internal thread for a 2″ filter – and the maximum possible aperture has been used throughout the connector to reduce (hopefully to zero) the slight vignetting I used to see on the old system.  Also Eric Kennedy (NTE Poole Ltd.) will be delivering the all-aluminium custom-built pier for the Paramount ME very shortly.  Next stage in the process will be the concrete support for the pier, the surrounding wooden decking, and finally the larger fibreglass dome to house the beast.  Hopefully this latter part of the project should be completed by end of June 2010.

Probus club talk 13th April 2010

Prof. Greg Parker will be giving a talk on “The Magic of Photography” at the Brockenhurst Probus Club on 13th April 2010.  He will discuss high-speed photography, photomicrography and of course deep-sky imaging with an accompanying PowerPoint slide show of his latest work.

Three screens with a Hubble desktop

So what does it look like in the NFO Control Room with the 3-screen system running a high-resolution Hubble image screensaver?

The velocity of light in vacuo

The extremely fast – but ultimately finite velocity of light in vacuo, strikes me as very odd.  Why does it have this particular value?  Wouldn’t it be very interesting if the finite velocity of light in vacuo is actually telling us something profound about the processing limitations of the Quantum Computer that generates our illusion of reality?

More things to know about high-performance graphics cards:

My old 2-monitor system (the one running XP with a graphics card that can drive 2 monitors) was playing up giving all sorts of odd (intermittent) effects including switching monitor 2 for monitor 1 and losing the desktop.  The card is fitted in one of these cases that doesn’t need screws – the card is held down by a plastic lever and the electrical connection to the case chassis through the metal end plate of the card was poor to say the least.  I used a screw to firmly fix the card to the chassis and all the intermittent problems have disappeared – so I guess that on these higher power cards (the ones that use an extra power connection on the card itself) there is a significant return current to the case  chassis from the metal end-plate of the graphics card.

Uncle Petros and Goldbach’s Conjecture:

By Apostolos Doxiadis – is a work of complete and utter brilliance, I would say genius – and a book that joins that elite (and very small) group of mine, the books that have been read in just one sitting.  If you have even the slightest interest in things mathematical, then read this book – it just might change your life – it certainly made me pause to reflect and brought back strong memories of a time when I was 19.

I recall the day clearly – I was sitting in my bedroom in Walkhampton (a village in Dartmoor National Park) and I was thinking long and hard about the subject I would take for my first degree.  If I was going to spend three long painful years learning something to the depths of my ability – then the subject had to be immutable, permanent, not something that could be disproved as our knowledge advanced.  The first subject that came to mind was mathematics, that’s it, I would take my first degree in mathematics – no question.  But in the back of my mind (I have no idea where I had read or heard of it) there was this thing called Godel’s Theorem, and although I knew nothing (in detail) about this, I was sure it meant that the subject of mathematics was not built on solid foundations.  Being only 19, and without the power of the Internet at my disposal (we are talking 1973) I decided in my ignorance not to take a degree in mathematics but instead to take Physics, after all if mathematics was flawed why not take another flawed subject?  And that’s how I ended up going to the University of Sussex in 1975 to take a first degree in Physics with Mathematics and Astronomy.  If you read Doxiadis’ book – you will see that Kurt Godel had a profound influence on many people with his Incompleteness Theorem 🙂

Professor Peter T Landsberg

It was Professor Peter Landsberg’s funeral today at the East Chapel at Southampton Crematorium.  Standing room only – Peter had a great number of friends.  He will be sadly missed – there is nobody at the University that can take his place at any level – truly the end of an era 🙁

Our latest deep-sky image: M44 the Beehive cluster in Cancer

Noel has just completed processing the 5 & 10-minute subs (probably around 8 hours worth in total) taken on the Hyperstar III of the Beehive Cluster – M44 – in the constellation Cancer.  At this time of the year we really only have Cancer objects in a really good imaging position as an early evening start is a little too soon for Leo.  The other problem is that there are really only two objects in Cancer worth going for – M44 & M67.  So maybe I will save M67 for next year as Leo is now getting itself in a good position and I need to get data all around M87 to add to our mega Markarian’s Chain mosaic.  Noel & Greg present you with M44 – the Beehive cluster in all its sparkly colour:

Three screens to go!

Here is a fish eye view of my three-screen system up and running.  Three superb Iiyama 24″ letterbox screens driven by an ATI Radeon 5770 card and one screen with a Sapphire (active) display port adapter from Overclockers U.K.  I suppose I should have had the Matrix screensaver running on the screens for the photo – but maybe that’s just a tad too geeky?
