ASA UWF1000 f1.3 Ultra Wide Field telescope system

Ideal platform for wide field imaging!

The UWF1000 f1.3 telescope is the ideal platform for wide field imaging and all-sky surveys. The UWF1000 f1.3 features a highly aspheric 5-lens corrector and motorized focusing with absolute encoders. The main mirror and the corrector can be collimated fully electronic to allow an easy and fast remote collimation.
The UWF1000 ensures precise focus and high-resolution data acquisition of the night sky – in the shortest possible time!

UWF1000 f1.3 Optical Layout

The UWF1000 uses a prime focus configuration. The main mirror is a high order asphere and in the prime focus we use a highly aspheric 5 Lens corrector to correct any field aberrations in a wavelength range from 400nm to 700nm. Only with these latest technological advances in optical design (aspherical surfaces, ED glasses), we could combine such a wide field with this short focal ratio.
It is definitely the best telescope if it comes to recording very faint objects with the minimal possible exposure time.

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.
