TeleVue star diagonals are manufactured to high quality standards and represent an important upgrade for any serious observer. Even the finest telescope can suffer from reduced performance if paired with a low-quality diagonal. For this reason, TeleVue designs its diagonals to maintain the full optical integrity of the system, ensuring that image quality from the objective lens to the eyepiece remains uncompromised. The DSC-0125 is a 1.25" 90° diagonal mirror featuring a 96% reflective aluminum coating.

The TeleVue 2x Big Barlow is a high-performance amplification lens designed to enhance magnification while preserving optical quality. A properly engineered Barlow not only increases power but also effectively slows the telescope’s focal ratio, which can improve eyepiece sharpness and overall image correction. In addition, it helps compensate for certain eyepiece aberrations, contributing to cleaner and more precise views. TeleVue Barlows are constructed using high-index, fully multi-coated glass elements to ensure optimal aberration correction, high contrast, and virtually no light loss.

The TeleVue Starbeam is a premium red-dot projection finder designed for maximum comfort, precision, and flexibility. Its unique flip-mirror mechanism allows viewing from straight-through orientation up to a 90° angle, making it comfortable to use whether the telescope is aimed low or high in the sky. When used straight through, you see the natural sky with a bright 10 arc-minute red “star” (approximately one-third the diameter of the Moon) marking the telescope’s pointing position.

The TeleVue Focusmate Driver is an adjustable-speed electric motor designed to enhance focusing precision on compatible TeleVue telescopes, including the NP127is. It installs easily onto the Focusmate unit and features a unique quick-disconnect mechanism, allowing you to switch between motorized and manual focusing without the use of tools. This flexibility makes it ideal for both imaging and visual observing. The system includes a battery-operated hand controller with forward and reverse buttons and a variable-speed control knob.

The TeleVue Encoder Kit is designed to equip compatible TeleVue mounts with digital setting circle capability. It provides all necessary components to integrate encoders into your mount, enabling precise position tracking when used with a compatible digital setting circle system. This kit is suitable for TeleVue Panoramic, Tele-Pod, and Gibraltar mounts. All required parts are included to ensure proper installation and reliable operation.
