In recent years, with the popularization of domestic astronomical knowledge 
and economic development, more and more domestic customers are not satisfied 
with a simple observation and photography, but need professional equipment to 
satisfy their yearning to explore the starry sky, leaving more gorgeous sky photos 
and observation images.

Starry Universe, Starry Skyscape

When shooting stars, the wide-angle lens is easy to achieve a broader perspective, especially make an effective
 and comprehensive full performance of the scene.

Quality Changes Life

Professional astrophotography telescope APO lens, the optical design of high quality 
image. The camera lens is easy to use and the two-end  focuser  is  used  for  high  precise  focusing.

    Our corporation has been in the astronomical telescope profession for many years, ASKAR is possessed of perfect technology and we have a professional R&D team. The ACL200mm F4 lens is specially designed and developed for the optimization of astronomical photography, the quality is excellent, and structure using an integrated design, which can achieve good results in correct exposure and the depth of field. When using this lens for astrophotography or scenery photography, the flat field intensity, uniformity, achromatic aberration and sharpness of image have attained a good effect, which bring amateur star gazer clear visual effects and more possibilities for photography.

ACL 200mm/4 The lens characteristics that

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.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. 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.A frame picture and bring function of flat field, effectively correct nearby star coma and distortion;

5.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. 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. 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.
