Aperture 90mm / focal length 600mm / f6.7: The TS 2.5" Flattener provides a fully illuminated and corrected field, even for full frame cameras. The flattener is being screwed directly to the M63x1 inside thread of the focuser. You need 2 tube segments (remove 1 part)

Aperture 90mm / focal length 450mm / f4.9: The reducer, calculated by Massimo Riccardi reduces the focal length and increases the aperture- focal ratio to f/4.9 while at the same time correcting the entire field for APS-C format sensors or KAF8300. Due to the very fast system, You can take photos of faint objects within one night. Even time-consuming LRGB images or narrow band imaging is no problem anymore. You need 1 tube segment (remove 2 parts)

Observing with Bino Viewer without Glass Path Corrector: Incredible rich field observation with both eyes without glass path corrector which increases the magnification - this offers this TS 90mm Apo. You will be able large deep sky objects and because of the very low magnification, you will have much light and a big field. Remove all 3 parts for long bino viewers or if you want to use a 2" diagonal or remove 2 parts, if you use a 1,25" diagonal.
