Design Features
Fast Focal Ratio
When used with the 60GT, the reducer accelerates the system from f/6 to f/3.9, dramatically reducing exposure times and increasing efficiency for deep-sky astrophotography. The effective focal length becomes 234mm, expanding the field of view for large nebulae and galaxies.
Uniform Flat Field
Corrects field curvature and coma to deliver sharp, round stars across the entire 44mm full-frame image circle.
Advanced Optical Design
A quadruplet lens configuration incorporating a Japan-made SD glass element effectively suppresses chromatic aberration, delivering high contrast and excellent colour correction.
