An ultra-fast refractor designed for discerning astrophotographers featuring a 5 element optical design. This f3.8 OTA is optimised for digital imaging.

The innovative wide and flat imaging field that covers 645 medium format cameras and 5 element, 5 group lens design completely eliminates the violet tint that can be caused by chromatic aberration. With an Super ED (SD) lens in the front objective group and an ED lens in the rear objective group, this scope achieves superb colour correction. The blue halos around stars, that can be visible in astrophotography and are hard to reduce with a 4 element, 4 group design, are well-corrected. In addition, astigmatism and coma aberrations are corrected to an extremely high level.

The Strehl ratio of the lens design of the VSD100F3.8 is better than that of a 4 element, 4 group design by approximately 10%. In addition it does not decrease significantly on stars away from the centre of the photographic field. The image circle is as large as 70mm in diameter (60% illuminated). Star images are as small as 15 microns around the corners, resulting in excellent field flatness.
