10000052: Levenhuk Ra R110 ED Doublet OTA

With the aperture of 110 mm (4.3 in), Levenhuk Ra R110 ED Doublet OTA is a very powerful refractor that produces sharp and clear images of observed objects with no chromatic aberration across the field of view. One element of the fully multi-coated apochromatic objective lens is made of ED glass with extra-low dispersion, which further adds to the quality of the produced views.

The edges of the apochromatic objective lens are blackened to eliminate the glare when observing brighter objects.

The optical tube is fitted with a dovetail mounting bracket that allows you to attach it to a mount or disassemble the instrument in a matter of minutes. The tube itself and the dual-speed Crayford focuser are made of aluminum, which makes the OTA lightweight and durable. Furthermore, the optical tube has a retractable dew cap that reduces light pollution and eliminates fogging of the objective lens.

Levenhuk Ra R110 ED Doublet OTA comes in a sturdy aluminum case that makes storing and transporting this optical tube safe and easy.
