StellaMira 106mm ED Quadruplet f/7 Flatfield Refractor Telescope

The StellaMira 106mm ED Quadruplet f/7 Flatfield Refractor is an advanced imaging telescope designed for astrophotographers seeking consistently sharp results across a wide range of celestial targets. By combining a four-element optical design with integrated field correction, it removes the need for a separate field flattener while delivering a naturally corrected image plane suitable for modern astronomy cameras.

At the heart of the telescope is a 106mm ED apochromatic optical system designed to minimise chromatic aberration and maintain excellent contrast. The use of extra-low dispersion glass helps produce clean, natural colours and tightly controlled star profiles, allowing astrophotographers to capture detailed images with accurate colour rendition and minimal unwanted halos around bright stars.

The 742mm focal length and f/7 focal ratio provide a highly practical imaging configuration. This focal length sits in a versatile range, offering enough image scale to capture detail in many galaxies, nebulae, and clusters while still providing a sufficiently wide field for larger deep-sky objects. The relatively fast f/7 design also helps reduce exposure times compared with slower refractors, making it an efficient choice for modern deep-sky imaging workflows.

A key advantage of the quadruplet optical design is the integrated field flattener, which corrects the natural curvature found in many refractor systems. This results in sharp stars from the centre of the frame to the edges, making the telescope particularly well suited to cameras with larger sensors, including full-frame DSLR, mirrorless, and dedicated astronomy cameras.

The StellaMira 106mm ED Quadruplet is built with astrophotography in mind. The precision 3.2″ dual-speed rack-and-pinion focuser provides smooth operation and accurate fine focusing, while offering the rigidity required to support imaging accessories such as cooled cameras, filter wheels, and guiding equipment. The focuser rotation system allows convenient camera orientation adjustments when framing targets or composing images.

The telescope’s compact optical tube design makes it attractive for imagers who want high-quality results without moving to a larger and heavier refractor system. Its combination of aperture, focal length, and optical correction makes it suitable for a broad range of deep-sky imaging applications, from expansive nebulae and star fields to smaller galaxies and galaxy groups.

Although designed primarily as an astrograph, the StellaMira 106mm ED Quadruplet also performs very well for visual astronomy. The flat-field optical design provides excellent edge-to-edge sharpness when observing rich star fields and open clusters, while the ED optics deliver high-contrast views of the Moon, planets, and brighter deep-sky objects.

Combining integrated field correction, ED apochromatic performance, and imaging-focused mechanics, the StellaMira 106mm ED Quadruplet f/7 Flatfield Refractor is an excellent choice for astrophotographers seeking a refined, versatile telescope capable of producing consistently high-quality images.
