ASA UWF300 f1.3 Ultra Wide Field telescope

One of the fastest telescopes of the world!

The UWF300 f1.3. telescope offers a groundbreaking optical design and is ideal for short exposure, high SNR wide field surveys. The main mirror works with absolute encoder feedback and can be collimated fully electronic for an easy and fast remote collimation.

UWF300 Optical Layout

The UWF300 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 ultra short focal length and wide field it is the ideal telescope for fast sky surveys searching for brighter objects. The resolution with modern small pixel CMOS is nevertheless surprisingly high even with such a short focal length. It can also be arranged in arrays on our DDM mounts.

Optional DDM100 Mount

Since the back focus is restricted, ASA can offer suitable CMOS/CCD cameras for this system. 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/1.3 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. *1) 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.

erläuterung

As the below image demonstrates, the UWF300 reaches a unprecedented resolution for a telescope in the 400mm focal length range and shows details and first bright stars in M31 even in 10s exposures)

Mechanics

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. The electronics for the collimation and focusing is attached to the tube. The total weight of the OTA is 31kg.

ASA Accessories

Remote package pro

Package for remote control and operational safety for your observatory equipped with an ASA telescope system.
The remote package contains an IP Camera mounted inside the Dome to remotely view the Telescope and an Uninterruptible Power Supply (UPS). The IP Camera allows to always view the telescope orientation to give you situational awareness of the observatory status. The UPS allows the telescope to keep operating during shorter (<30sec) power interruptions and to safely park the telescope in the event of a longer power outage.

Weather station sensor package

Operational safety for your in different weather conditions.
This package contains sensors for sky and ambient temperature, rain and humidity and wind speed plus all necessary mounting material.
This package guaranties operational safety of your observatory in case of unsuitable or hazardous weather conditions. It also provides the operator with a web interface to monitor and log weather events.

All Sky Cam 0201171A

An Allsky Camera is a quality of life feature every Observatory should have, it vastly improves the ability to gauge the weather conditions and also generates time lapse videos for evaluation and advertisement. This package contains an Allsky Camera with 180° FOV and 3100×2100 Pixel sensor size plus all mounting material.
