Product Overview
Askar ACL200 is an optical device
especially for optimizing the quality of astrophotography, while it also caters
to the needs of ground imaging. It's compact,
lightweight and easy to operate, an ideal combination of astrograph and camera
lens. The optical outcome is to be dramatically improved as the distortion
around the edge and achromatic aberration are greatly controlled. Askar ACL200
will bring you sharp and excellent celestial images together with a better
experience of exploration.
You will no longer worry about the vagueness of the images stemming from vignette or achromatic aberration. Askar ACL200 full frame astrophotographic lens with built-in flattener can help you solve cromatic or other aberrations. Relatively fast f/4 focal ratio can effectively shorten exposure time and reduce the astrophotographic burden of the equatorial mount due to long-time tracking.
