ASA Telescopes

ASA WF1000 f2.5 Wide Field telescope system

Ideal platform for widefield imaging!

The WF1000 f2.5 telescope is the ideal platform for wide field imaging and all-sky surveys. The WF1000 f2.5 features a 5-lens corrector and motorized focusing with absolute encoders.
The main mirror can be collimated fully electronic to allow an easy and fast remote collimation.
The WF1000 ensures precise focus and high-resolution data acquisition of the night sky – in the shortest possible time!

UWF1000 f2.5 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 5 Lens corrector to correct any field aberrations in a wavelength range from 400nm to 700nm. This prime focus telescope achieves the large field through a larger possible field diameter, enabling the usage of the largest available CCD/CMOS cameras with up to 95x95mm2 sensor size.
The larger focal length will be an advantage if it comes to resolution and pixel scale, or if you plan to use CCD cameras with larger pixels

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.
