Following the Askar N160, ASKAR updates the same product line with a larger-aperture Newtonian reflector telescope—the Askar N210. This new model boosts the clear aperture to 210mm, and while retaining the solid craftsmanship and excellent handling of the N160, it further enhances light-gathering capability and imaging quality. Specifically designed for deep-sky astrophotographers who demand higher image quality, it offers a cost-effective choice for those looking to upgrade to a large-aperture Newtonian telescope.
