近年来，随着国内天文知识的普及以及经济的发展，越来越多的国内客户不满足于简单的观测及拍摄，需要专业的器材来满足对于探索星空的向往，留下更加绚烂的星空照片及观测影像。

在拍摄星空时，广角可以吸纳更多的视角，
特别是容易引入前景，让画面更饱满。

专业天文摄影望远镜APO镜头，高品质恒星图形的光学设计
相机镜头使用简便、两头聚焦器模型用于高精度对焦

ACL 200mm/4镜头特点说明

1.世界首创200mm焦距天文专业摄影相机镜头，采用相机镜头外观及构造，一体化设计，紧凑轻便、简单易用；
The first 200 mm focal length astronomical professional photography camera lenses, camera lens appearance and structure, integrated design, compact and lightweight, easy to use;
2.针对星点优化毫不妥协的光学设计使得拍摄星空无需繁杂的附件设备，使用上与一般相机镜头无太大区别；
In view of the object in optimizing the optical design makes no compromise of light shooting stars without attachment devices, with general use camera lens has no much difference;
3.色差控制优异，再不用担心一般相机镜头和天文望远镜产生的色差光晕而带来模糊的成像；
The color difference control is excellent, and don't have to worry about general camera and telescope produce off color halo of fuzzy imaging;
4.全画幅画面，自带平场功能，有效纠正周边星点彗差及畸变；
A frame picture and bring function of flat field, effectively correct nearby star coma and distortion;
5.对于天文摄影来说，F/4属于快焦比，有效缩短曝光时间，减轻赤道仪长时间跟踪精度负担；
For astronomical photography, F / 4 belong to the fast focal ratios, shortening the exposure time effectively, reduce the financial burden on equatorial tracking accuracy for a long time;
6.针对星空摄影，采用两组调焦模式：模式一为粗调焦，模式二为1mm精细调焦，使得对焦点不再成为难题；
In view of the sky photography, using two groups of focusing mode: a model for coarse focus, fine focusing mode 2. 1 mm, makes the focus is no longer a problem;
7.针对景物摄影特别做了光学优化设计以及加入了F/4—F/22的光圈设计，使得在拍摄星空的同时也可以用来进行地面景物摄影，一举两得，最短对焦距离为3米。
In view of the scenery photography in particular the optical optimization design, and joined the F / 4 - F / 22 aperture design, made in the shooting stars at the same time also can be used for ground scenery photography, kill two birds with one stone, the minimum focus distance is 3 meters.
