Clearly, these are very important qualities in the UK’s maritime climate. Unlike traditional Dobsonians, the ES Ultra Light range dispenses with plastic-coated, dense particle board construction in favour of powder-coated aluminium for strength, lightness and resistance to corrosion without the moisture-absorbing qualities of chipboard. Each is modular in design, breaking down into compact, easy-to-assemble units for ease of transportation in even a small car to set up at dark-sky sites. The smaller models are both f/5, while the larger are f/4.6 and f/3.6, respectively. JOC owns a number of familiar company names, including Bresser in Germany and Explore Scientific (ES) in the USA.Įxplore Scientific currently sells a range of truss-tube Ultra Light Dobsonians encompassing four models of 254mm, 305mm, 406mm and 508mm aperture. Better known in the West as simply JOC, it’s one of the largest optoelectronic manufacturers in China. John Dobson lived in the United States from the age of 12, but he was born in Beijing, some 2,000 kilometres north of the city of Guangzhou, currently headquarters of Jinghua Optics and Electronics Co., Ltd. It took nearly 300 years from Sir Isaac’s original proof of concept before John Lowry Dobson (1915–2014) created the minimalist fusion of Newtonian optics with a stable, easy-to-use mount, and hence the Dobsonian was born. Yet even the best telescope is useless without an effective mount and, depending on its sophistication, a mounting can cost many times the cost of the instrument itself.
However, not every observer possesses the practical skills (or inclination) to grind and polish their own mirrors, so a little background reading quickly informs you that it’s hard to beat the performance-to-cost ratio of a Newtonian when seeking the largest quality telescope for your money. The elegant simplicity of Isaac Newton’s two-mirror reflecting telescope design from 1668 has inspired generations of amateur makers.
