Sharpstar 100mm f / 5.8 fully-multi-coated quadruplet flatfield apo FPL53
Sharpstar 100Q ED APO refractor telescope optics tube assembly is quadruplet four groups optical design, which includes one FPL-53ED glasses and air-spaced fully- muti-coated.Four-element optical design makes Sharpstar 100Q ED APO have good shot and eyes visual function,not less than the 44mm image circle can be competent the 35mm scope of the good as whole picture camera on the general market sells, make you have unparalleled shooting quality. Using super low dispersion ED glass (FPL-53) make the control of that color difference be excellent, not only in high quality photography get reflection, but make 100Q observation into a new realm. Acutance,contrast and the color control have a very good performance.
Due to Sharpstar 100Q ED APO adopts suitable focal ratio,that provides a excellent observation and the shooting system,making excellent color control, star sharp, images more clear.
Sharpstar 100Q ED APO in providing excellent optical system,but also provide an impressive focus system, Sharpstar 100Q ED APO has a dual-speed 3 inch tooth focusing device,focusing ratio of 1:10,compared Many in the market than the toothless refractor focusing device is used for toothed load greater focus, more fastness, so that you observed the use of heavy shooting in the attachment, no longer focusing device for the slip, out of focus to worry about. In addition, the distribution of the 360-degree rotating camera angle allows you to easily rotate, shoot their satisfaction with the work.
Even more importantly, its 3 inch focusing tubes is more sturdy and more stable compared with most commercially available specifications of 3inch focusing tubes, and it provides a good support for updating large-diameter flat field,focal reducer and many heavy attachments later.
