Tecnosky Apochromatic refractor AP 130/900 SLD OWL Triplet OTA (68934)

This apochromatic refractor uses a triplet lens system made with Ohara FPL-53 glass, a lanthanum element, and another low-dispersion glass. This combination delivers excellent color correction, even when observing very bright objects. The latest version features a newly designed lens cell for greater thermal stability and a lighter tube. The interior of the tube has a matte finish and includes lens hoods to minimize stray light.

With this high-quality apochromat, you have many options:

High-Resolution Observation: The AP 130/900 can split double stars and reveal fine details on the Moon and planets.

Deep Sky Observations: The 130 mm unobstructed aperture and high-contrast, color-corrected optics make it enjoyable to observe nebulae, star clusters, and galaxies. Stars appear sharp and pinpoint.

High-Magnification Photography: Using a quality 4x Barlow lens, you can capture the Moon and planets with remarkable detail.

Deep Sky Photography: When paired with a flattener or reducer, this telescope provides excellent results for deep sky imaging due to its high color correction.

The large drawtube fully illuminates full-frame cameras and allows for precise focusing with a 1:10 fine adjustment. The integrated field rotator enables you to rotate your camera to the desired position for the best framing. The focuser accepts 2-inch accessories with a self-centering locking system, and the same system is used for the 1.25-inch adapter, ensuring accessories are always centered, even when wearing gloves.

The redesigned tube rings are compatible with both Vixen and Losmandy-style dovetail rails. A comfortable carrying handle is mounted above the rings, making it easy to carry and providing a place to attach additional accessories such as guidescopes.

All OWL series apochromats come with an interferometric measurement log, guaranteeing a Strehl value of at least 0.95.

A sturdy carrying case is included.
