APOCHROMATIC Esprit 120ED eyepiece owners can now image with a reduced focal length. Although the nominal f/7 focal length is not excessive, it is always appreciated to be able to reduce exposure times or increase the signal-to-noise ratio (the focal length ratio then becomes f/5.4).

- Number of lenses: 3 (FMC - Fully Multi Coated multilayer treatment)
- Backfocus: 55mm
- Image circle corrected (for APS-C): 34mm
- Female threading for 2" filter: Included
