Mid size 71mm flat field refractor

This catalog highlights a 71mm refractor that balances light-gathering power with portability. The quadruplet air-spaced APO design is intended to provide a flat field without the need for additional external correctors. This simplifies the imaging train for photographers, making it easier to achieve sharp focus across the entire sensor area.

Equipped with a 230mm Vixen dovetail plate, the telescope integrates easily with standard astronomy mounts. The F6.9 focal ratio is well-suited for a variety of targets, from bright lunar details to distant deep sky structures. The ED glass elements work to minimize chromatic aberration, resulting in natural color reproduction and high contrast.

The build quality of this tube assembly is designed for longevity and precision. It is a versatile instrument that performs well for both serious visual observers and those focused on deep sky photography. The 71mm aperture offers a noticeable step up in resolution from smaller travel scopes while remaining easy to handle in the field.
