OptikkAstro – Fokus & Linse

An indispensable tool for precise calculation and evaluation of optical telescopes and observing conditions. With OptikkAstro – Focus & Lens you can analyze the real potential of your lenses and eyepieces directly under the starry sky, without complicated optical tables.

Maximize the image clarity of your night observations through three independent modules:

Magnification & Eyepiece: Enter focal length and aperture to find the exact magnification factor and check if the combination exceeds the telescope's physical diffraction limit.

Light Collection & Limit: Calculate how many times more light the telescope collects compared to the human eye, and find the maximum visible magnitude class based on local light pollution.

Atmospheric Seeing: Analyze how atmospheric turbulence and refraction affect the resolution in arc seconds, so you can choose the optimal equipment for planetary or deep space observations.

The interface provides a clean and structured overview inspired by professional observation logs in deep sapphire blue and star yellow tones.
