Askar 50P 50mm f/3.8 Quadruplet Petzval APO Refractor Telescope

The Askar 50P is an ultra-compact 50mm APO quadruplet Petval refractor designed for astrophotographers who value portability and performance. Its fast f/3.8 focal ratio makes it particularly well-suited for wide-field imaging and guiding, capturing expansive sections of the night sky with remarkable clarity. The optical design incorporates super low dispersion glass, delivering flat, color-corrected images that minimize chromatic aberration and maintain sharp detail across the field.

Despite its high-performance optics, the Askar 50P weighs just 3.1 pounds and features a compact body, making it exceptionally travel-friendly for on-location astrophotography. The telescope includes a 360-degree camera rotator, allowing precise framing without disturbing the setup, and an intuitive focusing ring that makes achieving crisp focus quick and straightforward. Compatible with APS-C sensors, the 50P balances speed, clarity, and portability, making it an excellent choice for both amateur and experienced astrophotographers seeking a versatile and reliable instrument.

Included with the telescope are essential accessories to get started: a tube ring, quick-release dew shield, front dust cap, 160mm Vixen dovetail, multi-functional handle, two finder bases, an instruction manual, a warranty card, and an inspection checklist. Together, these components provide a complete, ready-to-use package that’s ideal for capturing the cosmos with convenience and precision.

Askar 50P: Your compact travel imaging solution

The Askar 50P is particularly well suited for travel and deep sky astrophotography because of its combination of portability, fast optics, and wide field performance.

Portability and Travel-Friendly Design

  • Weighing only 3.1 pounds with a compact tube, it’s easy to pack into a carry-on or small travel case, making it ideal for trips to dark-sky locations.

  • Its small footprint allows it to fit on lightweight mounts or even travel tripods, reducing the need for heavy or cumbersome equipment.

  • The included 160mm Vixen-style dovetail and multi-functional handle make setup and transport smooth and secure, minimizing the hassle of frequent reassembly.

Deep Sky Imaging Advantages

  • The fast f/3.8 focal ratio collects light efficiently, allowing shorter exposures while still capturing faint nebulae, star clusters, and galaxies.

  • The quadruplet Petval design with super low dispersion glass produces flat, color-corrected images across the field, which is crucial for capturing wide star fields without distortion or chromatic aberration.

  • Compatibility with APS-C sensors ensures a broad imaging area, letting you capture expansive sections of the Milky Way, large nebulae, and open clusters in a single frame.

  • The 360-degree camera rotator allows precise framing, so even on the move, you can orient your camera for optimal composition without disturbing the telescope’s alignment.

The Askar 50P offers the freedom to travel light while still producing high quality deep-sky images, making it a strong choice for astrophotographers who want both portability and professional grade optics.
