Sharpstar 新推出的一體式望遠鏡Z4口徑為100mm,焦比f/5.5。使用了全鏡啞光灰色設計,單個抱箍上端自帶提手,方便攜帶和裝配。提手為卡槽式設計,可安裝有底座的尋星鏡等。Z4採用前三片加後三片的六片式設計,其中兩片為ED玻璃。與Sharpstar其他系列攝星鏡一樣,Z4也承襲了自平場設計,在使用時無需費心計算後截距,合焦即可進行拍攝。
Sharpstar’s new astrograph Z4 has an aperture of 100mm and the focal ratio is f/5.5 with matte gray coating. The tube ring has a handle on the top which is easy to carry and assemble. The handle is designed as a slot on which you can mount a finder base, etc. Z4 is a sextuplet astrograph with three pieces of lens at the front and three pieces at the back, and two of them are ED glasses. Just like other series of Sharpstar astrographs, Z4 is designed as self-flattened so there is no need to calculate the back focus. You can just make the target stay at the focus, and the optical system is perfect for imaging.
