Telescope Systems

ASA UWF600 f1.7 Ultra Wide Field telescope

One of the fastest telescopes of the world!

The UWF600 Astrograph has a super-fast 1.7 f-ratio, ideal for short exposure high SNR wide field surveys, possible to be combined on extra order with the ASA DDM200 Direct Drive mount fitted with absolute encoders.
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 is the perfect system for fully automated imaging operation.

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

Electronic

Our closed loop direct drive systems, sensor technology and observatory safety modules play a major role in achieving optimum results. All moving accessory components are equipped with high-resolution encoders and closed-loop feedback systems. We provide event timer modules, and customer updatable firmware.

Optic

Only the best for your telescope!

We believe that the most important part in producing optics is the testing. So ASA decided that we invest in the best test equipment available, remove any measuring error as good as possible and use real values in our specifications.

Technologie

Our mounts are manufactured with the lastest CNC technology.

Software

Platform independent control software.
