The new Sharpstar HNT Series reflectors T15028HNT-AL and T13028HNT-AL offer fast f/2.8 focal ratios, precise imaging capabilities, and practical design elements like built-in correctors and CNC-machined components. This release outlines their features and benefits for both enthusiasts and experienced users looking to improve their astrophotography setups.
The HNT Series T13028HNT-AL reflector stands out as a compact hyperbolic Newtonian reflector with a 130mm aperture and a fast f/2.8 focal ratio. Its lightweight aluminum tube and CNC-machined components ensure durability and portability. The primary mirror's 97% reflectivity and a 44mm full-frame image circle make it ideal for capturing detailed deep-sky images. Enhanced structural stability and a redesigned secondary mirror bracket ensure precise optical alignment and crisp diffraction spikes.
Focusing on stability and ease of use, the T13028HNT-AL features a dual-speed rack-and-pinion focuser that supports up to 3kg, with a built-in doublet corrector for aberration correction. Additional accessories, such as a Vixen-style dovetail plate and a finder base, enhance versatility. This model is a reliable choice for astrophotographers seeking precision and convenience.
The T13028HNT-AL excels in portability and precision with its compact design and 130mm aperture. Its highly reflective primary mirror and integrated corrector deliver excellent image clarity across a full-frame sensor. This model’s stability-focused design includes a CNC-machined secondary mirror bracket and a dual-speed focuser capable of supporting heavy imaging equipment.
Additional features, such as the Vixen-style dovetail plate, a finder base, and user-friendly adjustments for mirror alignment, make the T13028HNT-AL an accessible yet powerful tool for astrophotographers at any skill level. Its lightweight build and all-metal construction ensure long-term durability and reliability.
The T15028HNT-AL offers a step up with a 150mm aperture and the same fast f/2.8 focal ratio. Its Pyrex-alike PZ33 primary mirror delivers exceptional imaging performance, supported by a 44mm full-frame image circle and 97% reflectivity. Like its smaller counterpart, it features a CNC-machined secondary mirror bracket for stable alignment and sharp diffraction spikes.
Equipped with a dual-speed focuser, the T15028HNT-AL includes a built-in triplet corrector, ensuring superior aberration correction. The Losmandy-style dovetail plate and additional finder base enhance mounting options, while the robust aluminum construction ensures long-lasting performance. This model is tailored for advanced users seeking enhanced imaging capabilities.
The T15028HNT-AL builds on the strengths of its smaller sibling, offering a larger 150mm aperture for greater light-gathering power. Its advanced triplet corrector ensures exceptional aberration correction, while the CNC-machined components guarantee precise alignment and stability.
Tailored for demanding imaging tasks, the T15028HNT-AL supports heavier accessories with its Losmandy-style dovetail plate and robust focuser. With its all-metal construction and thoughtful design, this model is perfect for advanced astrophotographers aiming to capture detailed and vibrant deep-sky images.
