Returned item: Skywatcher Esprit-100ED Professional 100mm F/5.5 Super APO Triplet Telescope

Description: LINK

The Skywatcher Professional ESPRIT ED APO refractor is one of the fastest APO refractor telescopes in its aperture range. It offers maximum image quality thanks to its FPL-53 triplet lens, which is free of chromatic aberration.

With an aperture ratio of f/5.5, this telescope is particularly well-suited for astrophotography. We recommend using a field flattener, which corrects the image field and is also compatible with full-frame sensors.


The Skywatcher Professional ESPRIT ED APO refractor is one of the fastest APO refractor telescopes in its aperture range. Product Advantages:

+ Improved edge sharpness and color correction (color fringing or chromatic aberration) compared to a 2-element lens thanks to the 3-element OHARA lens

+ 3" CNC focuser with 1:11 reduction / LINEAR POWER principle

+ Superior multi-coating on the glass/air surfaces

+ Internal baffles to minimize stray light

+ Aluminum tube for rapid cooling

+ Weighs only 6.3 kg (without accessories)

+ Losmandy level prism rail and CNC tube rings
+ 2" and 1.25" adapters included

Please note:

-> For pin-sharp astrophotography across the entire field of view, we recommend using a field flattener.

This is screwed in, not clamped!

Please ask us – we're happy to advise you! A corrector is not necessary for visual use.

Included in delivery:

+ 2" dielectric star diagonal
+ 9x50 finder scope with upright and laterally correct image
+ Primer rail for Losmandy-style mounts and CNC clamps
