Product description

A high-quality apochromat for mobile use and travel

The heart of the refractor is the multi-coated objective with FPL53 apochromatic element from Ohara, Japan. This high-quality triplet lens with air gap provides colour-pure images even at high magnifications.

The objective with air gap is, of course, mounted in an adjustable position. Each lens is provided with the manufacturer's best possible multi-coating for maximum contrast. The focuser can hold accessories weighing up to approximately 5 kilograms without tilting. The extension tube is adjusted via a rack and pinion mechanism. It is decoupled from the bearing itself. This allows for sensitive adjustment even at maximum load. The 1:11 micro reduction gear also offers precise adjustment for astrophotography. An M54x0.75 internal thread on the extension tube also allows screw connections.
