[size=4]Ron Arbour自己制作的性能优异的16” f/5 Newtonian(陪伴他走过25年,最近完成自动化改造)并用它取得许多重大发现[/size]

V$Qv*i/w8S*g [size=4]介绍:[/size]
q+p#yvo [size=4][color=black]My interest in astronomy began at the age of two when my grandmother taught me some star names and constellations. Unusually, I was a telescope maker before I became interested in observational astronomy. At the age of twelve I made a 33mm spectacle lens telescope in a cardboard tube with a jewellers monocle and two years later, observed the close opposition of Mars in 1956. Not knowing that a dust storm was in progress, I blamed the small telescope for not showing any surface features and decided to make a 6” mirror and telescope. Some 50 years later I am still making telescopes. [/color][/size]V ~&]{:x/xG'NZ
[align=center][size=14pt][size=4][color=black]Telescope making had always been my main interest but this was about to change quite dramatically towards the end of the 1960’s. As my telescopes became more sophisticated I took a keen interest in astrophotography. It soon became apparent that I had to improve my skills in engineering – I bought a small lathe and taught myself to turn metal![/color][/size][/size][/align]I,W:u#P'r@

[align=center][size=14pt][size=4][color=black]As my telescopes and photography improved, I was persuaded by Harold Ridley and Michael Hendrie, both expert comet photographers having  worldwide reputations, to try some work on comets and minor planets. It was then that I found ‘serious’ work could also be fun and, more importantly, challenging. To counteract a comet’s motion relative to the background stars, I designed and built the world’s first computerised, comet-tracking camera. (Published in the BAAJ, Sky& Telescope Oct 87  and  PULSAR  May - Jun 1986.[/color][/size][/size][/align]
]JO:t K r9k l [align=center][size=14pt][size=4][color=black]Always trying to perfect the performance of telescopes, I took up long exposure astrophotography to seriously test my drive systems. I then drifted into, what I call, my ‘Stargazing period’ with a very keen interest in taking pretty pictures. To this end I built my own cameras, several of the cooled emulsion variety of my own design have been published in the Journal of the BAAJ 1979 Oct. and elsewhere.[/color][/size][/size][/align]
/xALS7I^*{{2Za [align=center][size=14pt][size=4][color=black]All this changed dramatically one night in the mid 1970’s. I terminated 3 exposures of M66 early because the guide star drifted too much. After developing the negatives and comparing the results with pictures in a textbook, I noted what appeared to be a star that was not present in the book’s image. Although it proved to be a bright HII region, it fired my imagination and started my obsession with supernova (SN) searching.[/color][/size][/size][/align]6ll M {T
[align=center][size=14pt][size=4][color=black]I spent some 20 fruitless years SN searching using photographic emulsions and the manually operated 16” Newtonian with which I was able to pioneer unguided photography by using a friction roller drive and programmable quartz drive unit. The tracking rate was adjusted to allow for refraction by reference to a computer program that I wrote for the purpose. This was published in Sky & Telescope Nov. 1989.[/color][/size][/size][/align]-ym

[align=center][size=14pt][size=4][color=black]1997 I purchased a 30cm LX200 and modified it considerably. Although the image quality is inferior to the Newtonian, the ‘GOTO’ facility is vital for my SN hunting. With my friend, David Briggs, I have written software for my RiscOS (non-IBM compatible) computer to automate the Meade and conduct the only fully robotic patrol from the U.K. Not only does the scope slew to a list of available galaxies and take an image of each one, but it also loads the appropriate master image and blinks the pair automatically. The only thing it cannot do is automatic image subtraction – yet. The system is capable of 100 images per hour and well over 1000 per night.[/color][/size][/size][/align]

充满着英国16世纪钟楼风格的大镜子，和那个大堰帽，简直是古董级的人

还是牛饭厉害啊bb49 bbbb46 bbbb46 bbbb40

感觉好复古啊 ;P

英式赤道仪，我靠，那么大的齿盘！！！！！ 有那么高的精度？？！！！K"D+\9s*t cM7^k
