ASA UWF600_2 with DDM200 & pier

ASA UWF600_2+ + DDM200 + pier

One of the fastest telescopes of the world!

The UWF600_2+ package features two super-fast 600mm f1.7 UWF OTAs and our precision DDM200 mount in Twin Mode. It is the perfect system for fully automated high-end imaging operation.
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.
This system is ideal for short exposure, high SNR wide field surveys.

ASA DDM200 Mount

ASA ASA Direct Drive Technology with absolute encoders for high-end applications.

New design based on 15 years of experience with Direct Drive mounts. Ready for the most demanding applications in pointing and tracking accuracy, like laser comunication, satellite tracking and general astronomical research. Load capacity of 200kg/440lbs on a polar wedge.

UWF600 Optical LayoutUWF 600

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.

As with all these ultrafast systems, the system has to be optimized and assembled for a certain filter thickness. While other manufacturers will not care about filter thickness, we do know, that in a f/1.7 light beam even a flat medium with a refractive index <>1 causes spherical aberration which has to be included in the optical design for perfect image quality. The corrector is of course coated with a multi layer AR coating.
The field of view is given as diameter for which the performance was optimized. Since there exist no circular sensors, we often recommend to use a CCD with larger diagonal, since this allows a better usage of the optimized field.

The closed full tube is made of carbon fiber and includes a light shroud. The main mirror can be collimated fully electronic to allow an easy and fast remote collimation. As one of the first telescopes in the market, the prime focus image plane can also be tilted fully electronic with 3 ball spindles with absolute encoder. This allows a very easy adjustment (we know no CCD or CMOS which would have a internal alignment accurate enough to cover the full resolution of our prime focus instrument without tweaking the image plane tilt). The electronics for the collimation and focusing is attached to the tube. The total weight of the OTA is 150kg.
