This lens telescope is one of the largest apochromatic refractors on the market and ideal for observatories. Sharpstar continues its tradition of uncompromising value for money with this apo.
The triplet apo lens with air gap: The Askar APO series uses special optical designs and multiple lens elements to correct chromatic aberration, resulting in higher image quality. ED glass, also known as low dispersion glass, is an optical glass specially developed to reduce chromatic aberration.
Integrated tube extension: The tube has an integrated extension that can be pulled out or pushed in as required and locked in place with a clamping ring. This means that the APO can be used not only for photography but also for visual observation. The working distance is large enough for the use of a diagonal mirror and binocular attachment.
Focuser: The 3.5-inch rack and pinion focuser is compatible with most modern focus motors. The focus travel is 100 mm. The entire focuser is CNC-machined and has an anti-reflective coating on the inside. A scale makes it easy to set a specific position.
The large 360° rotator has precise scales for convenient adjustment and a large locking screw that is easy to tighten even under high loads. Adaptors for 2" and 1.25" accessories complete the equipment.
