Vixen Optics FL55ss overview

  • 1Description

Designed to deliver outstanding views of the moon and planets, the Vixen Optics FL55ss 55mm f/5.5 Fluorite APO Refractor Telescope is engineered with an array of features that work together to provide performance in a small package.

This apochromatic refractor design virtually eliminates chromatic aberrations, and is complemented by the use of extra low-dispersion fluorite glass and broadband fully multi-coatings that maximize light transmission across the entire spectrum and provide improved color correction, especially at the low end of the blue spectrum, and prevents halos with higher contrast. The fast focal ratio makes it ideal for imaging, and its large 44mm imaging circle will cover today's large camera sensors to enable you to capture full frame images without vignetting. With the addition of Vixen's option field flattener and focal reducer, the f/5.5 focal ratio drops to a stunning f/4.3 putting its imaging performance on par with an astrograph. The FL55ss is offered here without a mount or tripod, but comes with an included Vixen-style dovetail bar to make it compatible with the most common size of mount saddle plates.

Optical Tube Assembly
  • Compact 55mm aperture is ideal for observing and imaging the moon and planets
  • Fast f/5.5 focal ratio is ideal for astrophotography with reduced noise on imaging sensors and reduced exposure time versus slower scopes without sacrificing performance
  • Refractor-style light path
  • Apochromatic doublet lens design virtually eliminates chromatic aberrations
  • Extra low-dispersion fluorite glass provides improved color correction when compared to standard ED glass, especially at the low end of blue spectrum, and prevents halos with higher contrast
  • Anti-reflection broadband fully multi-coated optics maximize light transmission across the entire visual spectrum while improving contrast and clarity
  • Large 44mm imaging circle will completely cover large full-frame imaging sensors without vignetting
  • Resolution 2.11 arcsec
  • Rack-and-pinion focusing mechanism with 1.25" eyepiece holder
  • 60mm, 43mm, and 36.4mm adapter threads for directly attaching accessories like photo adapters
  • OTA only; mount and tripod required for proper use
  • Includes Dovetail Slide Bar to mount on Vixen-style saddles
