Vixen Telescope SD Flattener HD Kit

 

Features

Ready for taking great photos of deep-sky objects!

The SD flattener HD kit is designed for a flat focal plane to produce crisp image of stars with the SD series of APO refractors. It consists of a high-performance flattener lens and a connecting tube ring.

The SD flattener HD lens improves off-axis image quality greatly with a minimum change of the focal length. It covers a 44mm photographic field in diameter that is sufficient for the full-frame DSLR cameras.

The same anti-reflection AS coatings that are used for our high-end VSD100F3.8 renowned for extremely high light transmission (99.9% per surface) are provided on each of the lens surfaces of the SD flattener HD. Also, matte-finish is elaborate to eliminate internal reflections and loss of light completely.

If combined with a Reducer HD sold optionally, the focal length will be reduced by 0.79 times (F.7.7 to F6.1) without diminishing the image circle of 44mm. A result is sharp image throughout the photographic field of view.
