Fluorostar 132 in Space Gray: the top-class all-around apochromat
The William Optics Fluorostar 132 Space Gray combines a large aperture with exceptional sharpness. The FPL-53 and lanthanum glass triplet lens delivers a color-pure image where star points truly shine: double stars are sharply separated, and Jupiter's cloud bands and Saturn's rings are clear and sharp.
Lots of light, short exposures
With a 132 mm aperture and 925 mm focal length (f/7), you capture a lot of light: nebulae and galaxies require shorter exposures, and the image scale is large enough for serious planetary work. The 3.7-inch rotating focuser with 1:10 fine adjustment supports heavy camera trains without sagging and rotates the composition without loss of focus. Expect an EQ6-class mount.

For whom yes, for whom no
For advanced astrophotographers and visual observers seeking a refractor for life. Not for those who photograph with mobile or lightweight mounts; the Fluorostar 91 is the logical choice then.
