ASA (Astrosysteme) telescopes are world class, both in terms of optical quality and telescope design. A very rigid carbon tube in honeycomb technology and CNC machined aluminium components.

Telescope in very good condition (small scratches on the tube). Optics are perfect. I am the second owner of the telescope and know the first owner well.

In 09.2019 at ASA the telescope had an focuser upgrade (from OKZ3 to AAF3) and a full inspection. The new AAF focuser plus kontroler alone is a cost more than 3,000 EUR. I have the invoice.

AAF3 3” Focuser

"The ASA AAF3 manufactured to ASA's typically high standards in aluminium and carbon fibre. It weighs an extremely low 2kg yet has a high 9kg capacity and 30mm of travel.

Internally the focuser uses a stepper motor combined with a high resolution magnetic absolute encoder. This allows it to measure the focuser position directly on the inner focuser tube. The focuser also features an internal temperature sensor.

The focuser is intended to be used with a variety of adapters for attachment to the telescope and fitting cameras."
