Telescope-Accessories-Apertura 75Q 0.75x Reducer

The Apertura 75Q 0.75x Reducer – Upgrade Your Apertura 75Q Experience!

The team at Apertura continues to deliver high quality products designed to elevate your astrophotography, and have crafted this 0.75x reducer for your 75Q refractor! The lower focal ratio broadens your field of view, giving you increased imaging opportunities. Not only this, but by also lowering the focal ratio, the resulting images will have a higher signal to noise ratio and possess greater detail!

This 0.75x reducer takes the native focal ratio of f/5.4 and focal length of 405mm down to an incredibly fast f/4 and 303.7 mm focal length. Specs like these are hard to come by, turning this quintuplet into one the fastest and highest performing refractors on the market today. In comparison to the William Optics RedCat 61 with a similar focal length of 300mm, the Apertura 75Q paired with this 0.75x reducer offers 1.5x more light gathering power! Constructed with high quality glass, this reducer provides stunning colors, and is well corrected across the frame. This means you can enjoy sharp stars from corner to corner with APS-C sized sensors, as seen within this image of the North America Nebula. Installation is quick and simple on the 75Q refractor, includes M48 threads on the camera side, and features the industry standard 55 mm of backfocus.

Taking Your Refractor Experience to New Heights

Improving upon the already outstanding optics of the Apertura 75Q, the addition of this 0.75x reducer turns this quintuplet refractor into a telescope of unrivaled quality! The 75 mm in aperture, 303 mm focal length, f/4 focal ratio, and five internal lens elements is unheard of at this amazing price point, making for a high performance refractor perfect for any astrophotographer. Capture large regions of the sky within a single exposure, and produce stunning images brimming with clarity. Thanks to the ingenuity from the team at Apertura, quality has never been more accessible.
