Askar N210 210mm F3.4 Newtonian Reflector Telescope with 0.95x Triplet Corrector

Following the Askar N160, Askar expands its fast Newtonian product line with the larger-aperture Askar N210. This new model boosts the clear aperture to 210 mm, retaining the precision craftsmanship and solid handling of the N160 while significantly enhancing light-gathering capability and optical resolving power. Specifically tailored for deep-sky astrophotographers requiring high-contrast imaging performance, the N210 serves as a powerful, cost-effective upgrade to large-aperture fast reflector systems.

(Solar Warning: Solar observation requires a dedicated, certified solar filter mounted securely on the front of the telescope. Never point the telescope directly at the Sun without an approved solar filter attached.)

【Key Features & Technical Highlights】

• 210 mm Parabolic Primary Mirror: Offers massive light-gathering ability and a fine optical resolution of 0.55 arcseconds to capture faint deep-sky structures with minimal exposure time.

• Ultra-Fast F/3.4 Speed (with 0.95x Triplet Corrector): Ships with a dedicated 0.95x triplet MPCC corrector that reduces focal length to 714 mm at F/3.4, yielding a corrected image circle for APS-C sensors (28 mm).

• Carbon Fiber Tube Construction: Machined with a lightweight carbon fiber tube (OTA weight 7.9 kg), delivering superior thermal stability to minimize focus shift during long exposure sessions.

• Standard 55 mm Back-Focus: Features an M48x0.75 rear thread interface providing standard 55 mm back-focus spacing for simple camera train integration.

• Comprehensive Accessory Package: Includes a 400 mm dovetail bar, multifunctional carrying handle, tube rings, and precision shim sets (0.1mm, 0.2mm, 0.3mm) for exact back-focus fine-tuning.
