Maksutov-Cassegrain 光學設計
如果您正在尋找具有高水平細節的清晰、對比鮮明的視場,Skymax 系列就是您的不二之選,它是 Sky-Watcher 的首屈一指的 Maksutov-Cassegrains 系列。 Maksutovs 通常被認為比 Schmidt-Cassegrains 能產生更清晰的圖像,它為天文學家提供了大視孔、高對比度和長焦距的緊湊型封裝。由於焦距比普通牛頓望遠鏡或折射望遠鏡長 5-7 倍,因此這些望遠鏡可提供更高水平的行星細節。
Skymax Maksutovs 的鏡子由硼矽酸製成,經過拋光並塗有我們專有的 Radiant™ 鋁石英™ (RAQ™) 塗層,可產生高達 94% 的反射率。所有 Maksutovs 都使用校正板來幫助減少色差,然後使用我們標誌性的 Metallic High-Transmission Coatings™ (MHTC™) 進行塗層,以實惠的價格生產專業級光學器件。
Skymax 180 包括2 英寸28mm目鏡、紅點尋星鏡、2英寸稜鏡、V 型鳩尾板一個軟質手提箱。
