ASA UWF600 + DDM200 + wedge

One of the fastest telescopes of the world!

The UWF600_2 combines the super-fast 600mm f1.7 UWF OTA with our heavy-duty DDM200 mount. This large aperture system is ideal for short exposure, high SNR wide field surveys.
The main mirror and the corrector can be collimated fully electronic to allow an easy and fast remote collimation. The focuser works with absolute encoder feedback.
It can be optionally upgraded with a second optical tube assembly when used in Twin Mode. Features an aspherical optic design.

UWF600 Optical Layout

The UWF600 uses a prime focus configuration. The main mirror is a high order asphere and in the prime focus we use a 5 Lens corrector to correct any field aberrations in a wavelength range from 400nm to 700nm.

With the medium focal length it offers a very wide field in combination with a high resolution, especially in combination with modern small pixel CMOS sensors. It can also be arranged in arrays on our DDM mounts and can be a cost effective solution compared to fewer, larger telescopes.

Technical Details

01 Electronics
