Hotech HyperStar Laser Collimator 9.25" / 11" (64685)

695.7 $

Tax included

Achieving precise star collimation typically demands ideal observing conditions: clear skies, calm air, stable temperatures, minimal light pollution, a well-aligned tracking mount, thermal equilibrium of the optical tube, and a suitably bright reference star. In practice, many of these factors are beyond the observer’s control. As a result, traditional star collimation often turns into a frustrating guessing game—moving between the front and back of the telescope, adjusting screws while peering through a high-magnification eyepiece at an unstable, defocused star image. The process can be time-consuming and unreliable.

Hotech HyperStar Laser Collimator 14" (64686)

695.7 $

Tax included

Achieving precise star collimation normally requires ideal conditions: clear skies, no wind, stable temperatures, minimal light pollution, a well-aligned tracking mount, thermal equilibrium of the optical tube, and a suitably bright reference star. In reality, these factors are rarely all present at the same time. As a result, traditional star collimation often becomes a frustrating trial-and-error process, moving back and forth between the front and rear of the telescope, adjusting screws while trying to judge concentricity through a high-magnification eyepiece as the defocused star image constantly shifts.

Hotech 2" SCA field flattener (22937)

280.11 $

Tax included

Refractor telescopes often produce optical errors toward the edge of the image field. This leads to field curvature, where stars near the edges appear blurred, distorted, or out of focus. Such curvature reduces image quality and is especially undesirable in astrophotography, where visual aesthetics and pinpoint stars matter. The Hotech Field Flattener offers a simple and effective solution to this common issue. Achieving sharp stars right to the corners of the image is possible with the Hotech Field Flattener—and it is remarkably easy to use.
