The High Performance
Apochromatic 3-element Objective
The triplet apochromatic optics structure (1 piece of S-FPL51 low dispersion ED glass + 2 pieces of correction glass) is adopted to significantly improve the image quality of the captured image (15.8% increase by the spectrometer calculation). Significantly reduces edge dispersion resulting in blue fringing problems.
2.5 inches 1:10 Dual-speed Focuser
The 2.5-inch focusing base can effectively reduce the vignetting problem when connecting to a full-frame camera, and the FPL51 APO can improve the quality of the captured images.
The Elimination Of Stray Light
4 extinction light bars are used inside the lens barrel, which can eliminate all stray light interference on the inner wall of the lens barrel.
