Omegon Reducer 0.7x for 72/400 Quintuplet APO

The Omegon Reducer 0.7x for 72/400 Quintuplet APO shortens the focal length of your apochromatic refractor from 400 mm to 280 mm. In the process, the aperture ratio changes from f/5.6 to a very bright f/3.9 system. This significantly shortens exposure times and allows you to capture more detail in less time - ideal for photography of faint deep-sky objects.

Designed specifically for the Omegon Pro APO 72/400 Quintuplet, the reducer delivers a fully corrected field of view suitable for both APS-C and full-frame lenses. Thanks to the high-quality FMC coating, light transmission remains high and stars are sharp right into the far corners of your image. The sturdy M68 connector ensures a stable connection to your telescope, while the M48 camera interface provides space for filters and adapters. With a back focus of 55 mm, the reducer fits perfectly with most astrophotography configurations.

Application

The Omegon Reducer 0.7x for 72/400 Quintuplet APO is ideal for wide-angle astrophotography. Thanks to its focal length of only 280 mm, you will capture vast expanses of sky, such as the Milky Way, the Orion Nebula or the Andromeda Nebula. The combination of speed (f/3.9) and correction makes this accessory indispensable for anyone who wants to capture high-quality deep-sky images with a compact APO.
