Introduction
My current permanent
telescope mount in the back garden used mostly for Solar astronomy. This
part of the website provides for my interest in Astronomy. This astronomy
interest began at about the age of 8 following a meteor shower while on holiday
in Wales. The perseids must have been magnificent, because a vague interest
became a hobby. Following that I was given a small 'toy' 50mm refractor
which was basically a source of frustration until i asked for and received for
christmas ( very lucky me ) the optical components for an 8" Newtonian
reflector telescope. The tube was a 10" land drainage plastic tube, the
mounting an undriven equatorial made from galvanised pipe, stainless steel
shafts and turned bearings made from scraps of gunmetal. The counterweight was
a lump of concrete cast in a bucket with some scraps of lead pipe to increase
the density.
And the view was fantastic.! Each summer we went camping in
Cornwall and the telescope went in the trailer on the back of the car. It
wasn't small. The only eyepieces I had were a wide-field eyepiece and a barlow
lens to up the magnification. The telescope was erected on the cover of a sess
pit. It was smelly but flat and away from tent lights . Maybe thats not so much
of a surprise.
Rossall School - the Assheton Observatory The next
step was to make much more use of the school telescope at Rossall. Rossall had
the Assheton Observatory which contained a 6" Cooke Troughton and Simms
refractor on a german equatorial mount driven by clockwork and descending
weights. Once overhauled by cleaning and repairing some of the damaged teeth in
the clockwork, the telescope and drive worked like a dream. Slow motion
controls were by use of 'endless' ropes over pulleys attached to the end of
worm wheels. The dome was a conical roof running on runners around the top
of a circular building and pulled around by pulleys in rope blocks. The
observatory iself is in the middle of playing fields in the school grounds and
thus as far away from bright lights as possible when located 4 miles from
Blackpool, Lancashire. Until the Blackpool illumination season came upon us
each year and then the laser mounted on Blackpool Tower could reach havoc.
Rossall School Assheton ObservatoryThe Rossall
telescope was where I became interested in photography throught the photography
club there. By hacking together a strip o metal and some jubillee clips around
the telescope focusser, I culd mount an SLR camera up to the telescope for some
pretty good results.
At Rossall I took the 'O' level in Astronomy that
was available as a syllabus from the London board. there was noone to teach it
so out came a textbook and a bit of study. The course involved an exam ans some
practical work: I ended up doing three practicals - one on the tracking of
sunspots, one on the Halleys comet apparation of 1986 and the last involved
lots of lunar photography. Not only that but we ( Peter Smith, Sam Gardener,
and others ) set up a small astronomy society with guest speakers and lots of
late evening observing. All of which set up a university degree
course....
University College London. University College is
located near to Euston Street station in Central London, at the top of Gower
Street. Their practical facilities consist of a pair of large telescopes and
numerous smaller refractors and reflectors in Mill Hill, 30 minutes north by
train. THe course covers a wide remit of Interstellar, solar, theoretical
and applied physics as well as all the support courses of maths, mechanics,
computer programming and such. Of course I'm sure a lot has changed by now.
Astronomy degreeI managed to fluke a viver on the High
Energy Astrophysics course and got a first. Infra red astronomy
instrumentation Ph.D. This was all about the application of fabry-perot
interferometer technology that had been developed for the ISO IR satellite at
long wavelengths and bringing all to bear at shorter IR wavelengths. It was all
liquid nitrogen in foam canisters, liquid helium in bright stainless steel
canisters and lots of programming in basic, C and assembler to write the
control software that made the instrument tune to a particular wavelength and
hold it there as the instrument cooled down to operating temperature at -273
degrees C. In the end I have to admit I ran out of time, will and money for the
cryogens to complete testing for a full write-up.
RAL So I joined the Rutherford Appleton Laboratory
as a CCD detector engineer, analysing project operation requirements and
creating electronic and mechanical designs for camera systems, both those meant
to fly on satellites and on the ground. Examples of this include:
- The design of the water-cooled Durham University Adaptive
very high - speed CCD imager mechanical housing for use on the Gemini
Telescope.
- the CMOS imager housing and illumination used to monitor
the satellite behaviour inside the vacuum test environment at space
temperatures of -200 degrees °C. This rig was used to inspect the behaviour
of control mechanisms during satellite assembly tests.
- the Rosetta lander module designed to land on Comert
Berrelli - work involving designing alternative, micro-miniature mass
spectrometer subsystems using piezo-electric gas valves.
- Design work for the infra-red camera aboard Rosetta main
spacecraft bus
- Design specs and data modellling for an X-ray CCD camera
to go on the ESA M3 MORO mission to re-map the moon.
- Design work on efficient peltier cooling of ccd
cameras.
- Assembly and Testing of the two Jet-X orbiting X-Ray
observatory guidance cameras for guide-star acquisition and observatory
pointing.
- Data modelling on stellar distribution and brightness
compared to CCD camera speed and field of view for design of spacecraft star
acquisition pointing systems.
Active Silicon
-This company ( found here on the web ) provided interface cards
for widely used OS/hardware combinations to allow image acquisition from
scientific and industrial video and CCD cameras. Here I wrote the LynXOS port
of the camera interface card library and drivers. LynxOS was a real-time UNIX
OS for X86 and PowerPC machine ( Remember the G3? ).
The driver was designed to compile for LynxOs on X86 and PPC
by use of simple compiler directives. The test suite also included a powerful
and simple X-windows interface.
The video acquisition side then branched out into Casino
chip real-time identification and sorting using a video system to image the
cips on a high-speed coveyor and control subsequent processes to sort them into
bins. Here i provided the camera housing design which included a purpose-built
flash gun. Similarly I also provided the mechanical and PIC embedded processor
software designs for a roulette wheel landing-zone detector. How else do you
think you can play roulette over the internet?
