About this product

Model:  skywatcher_flattener_esprit_120_20189
Part Number:  20189

An optically-matched M48-fitting doublet field flattener for Sky-Watcher's Esprit 120 ED PRO triplet refractor. 

The M48 fitting provides a large clear aperture to reduce halation and a precision thread ensures the triplet and doublet lens groups are precisely aligned on the optical axis perpendicular to the image. 

When used with the field flattener the Esprit-120 ED PRO's imaging circle is 44mm.

Notes 

  • When fitting a DSLR camera you need only a M48 Ring to suit your Canon or Nikon camera. No additional spacers are required.
  • The spacing for dedicated CCD imaging cameras is 75mm from mating surface. 
  • The rear thread is M48. When using T-threaded accessories you will need a FLO M48-T adapter.
