Askar 50P Lightweight Professional Astronomical 50MM Aperture F/3.8 Telescope Quadruplet Petzval APO Structure

Description:
- The 50P is a compact OTA that combines a 50mm aperture, 190mm focal length, and a fast f/3.8 focal ratio into a lightweight, portable form -- delivering professional optical performance in a minimal footprint.
- Its optical system employs a quadruplet Petzval APO design, featuring one SD glass element. The rear two elements are cemented,supporting APS-C format and optimized for 1-inch sensors. Thanks to the self-flattened design, no additional correctors are required: attach your camera, achieve focus, and begin capturing flat-field images.
- The lens tube is built as a single lightweight unit. The lens hood adopts a design: extended during use to block stray light effectively, and reversed when stored to minimize overall length. Combined with the dust cover, it offers both convenience and protection.
- Dual finder bases are integrated on both sides of the tube ring, and multiple standard M4 threaded holes are reserved, offering ample potential for expanding with astronomical accessories.
