Askar FRA400C 0.7x Full-Frame Reducer
Upgrade Your Askar FR400C Refractor with this Reducer!
Looking to enhance your Askar FRA400C experience? This 0.7x reducer is the perfect solution! Offering expanded views of the night sky, enjoy resolving large, sweeping scenes of nebulosity and other cosmic vistas. The triplet design and full-frame, flat imaging field delivers quality consistent with the high performance Askar FRA400C, making it a valuable addition for those seeking a wider field of view.
A 0.7x reduction rate brings the native focal length of 400 mm down to 280 mm. This not only increases your scope of vision, but enables faster light collection thanks to the speedier f/3.9 focal ratio! With more signal gathered per given exposure time, you can expect a higher signal-to-noise ratio for better defined detail within your frames. Installation of this Askar FRA600C 0.7x Reducer is effortless, and the industry standard of 55 mm of backfocus makes camera attachment a piece of cake.
