Detailed Description

The StellaLyra 10" f/4 M-LRN Newtonian Reflector is a powerhouse for deep-sky imaging, meticulously designed and crafted for both amateur and professional astronomers. The 10" aperture allows for significant light capture, ensuring bright and detailed images of the night sky.

Its parabolic primary mirrors, coated with aluminium and silicon dioxide, guarantee minimum 93% reflectivity, preserving the mirror's brightness for years. These mirrors, coupled with the 70mm minor axis secondary mirror, provide sharp and clear views of celestial objects.

The sturdy dual-speed 3" Linear Crayford focuser supports small to medium imaging payloads, allowing for precise and smooth adjustments, enhancing the overall imaging experience. The included 8x50 straight finderscope, with fully multicoated optics, can be adapted for use as a convenient guide-scope, adding versatility to your stargazing sessions.

For those who prefer visual astronomy, the telescope comes with an adapter for 2" & 1.25" eyepieces and a 35mm focus extender. The metal tube-rings and Vixen-style dovetail mounting plate ensure easy and secure setup.

Note that for optimal astrophotography results, a coma corrector is recommended. The recent 2024 update includes an improved focuser with a flat base, simplifying the attachment of an EAF bracket.

Benefits

• Ease of Use: Chunky collimation knobs and integrated fan for hassle-free setup and quick cooling.
