The Artesky 650nm laser collimator is crafted from brushed aluminum with a precisely calculated diameter of 2" (50.8mm), fitting perfectly into your focuser!

The projected laser beam, certified with a wavelength of 650nm, is very thin and well-defined so you can perform collimation both at night and during the day.

Incorporating a solid-state laser diode, the collimator maintains its integrity over time and usage, factory-aligned to 10 arcseconds during production, ensuring an accuracy of 1.2mm at a distance of 10 meters.

Built to withstand shocks to maintain alignment - even when dropped - this collimator is factory collimated, retaining alignment despite transport and use. A convenient shockproof carrying case is included to prevent potential impacts.

The Artesky 650nm laser undergoes an extensive design process before being brought to market, evident upon seeing the product.

Within the collimator lies a solid-state laser diode, emitting an intense laser beam through a front aperture, precisely along the central axis of the collimator's cylindrical body. This beam serves as a "reference line" for alignments. It's crucial for a laser collimator that the beam aligns with the cylindrical axis, as misalignment would result in off-center and asymmetric optical alignment, producing aberrated images.

The front aperture has a diameter of 1.00mm, further narrowing the laser beam for a perfect point.

Powered by two easily replaceable AAA batteries, the Artesky laser enables precise collimation of your Newtonian or Ritchey-Chrétien telescope, resulting in sharper images, increased contrast, and revealing even the faintest details of the night sky.
