Eyepiece Tecnosky Ultra Flat Field 15mm 65°

Eyepiece Tecnosky Ultra Flat Field 15mm 65°

After the success of the Flat Field eyepieces, now comes the Ultra Flat Field series; thanks to the new optical design the apparent field is increased but without worsening the quality at the edges, indeed they are very contrasted and corrected on difficult instruments such as newtons and short focal length refractors.
The 15 mm focal length is made up of 8 lenses in 5 groups, all covered by FMC! The apparent 65° field places it between the Super Wide Angle eyepieces but with a greater correction and a still light and compact body, in fact it weighs only 136 grams
The eye relief of 16mm makes it usable also for spectacle wearers but without the uncomfortable parallax effect
