Skywatcher Esprit 120ED - 120 mm f/7 FPL53 ED Triplet Apochromat
We are proud to present the new apochromatic 120 mm 3-element ED refractor telescope Skywatcher Professional Esprit 120. It is a refractor telescope of the highest quality with an optical performance that is on par with the leading, comparable devices of the well-known and famous high-end manufacturers.
The ESPRIT apo triplets are designed for the most demanding astrophotographers, but are also fine telescopes for visual observations. The premium, superbly-corrected optical systems deliver high-contrast images full of detail and zero detectable colour fringing, even on the brightest of objects. The 3" LPF focuser allows a high payload of 5 kg without shifting during focusing. The 11:1 gear reduction allows exact focusing even on critical objects.

3-element objective lens, aperture 120 mm, focal length 840 mm, focal ratio f/7 zero detectable colour fringing due to Ohara FPL53 APO element 3" CNC-machined 11:1 dual-speed Linear Power focuser, rotatable! Zero focus-shift during focusing Best possible multi-coating on every glass-air surface Knife-edge baffled optical system aluminium OTA material (superior to plain carbon-fibre for this application) OTA weight only 10.3 kg (without accessories) Fixed dew shield, diameter 150 mm Drawtube with 2" and 1.25" eyepiece adaptors and indexed scale CNC tube rings with Losmandy style dovetail The optional flattener is screwed, not clamped Dew shield diameter 165 mmThe 3" Linear Power Focuser:
The 3" Linear Power focuser is clearly superior to conventional Crayford focusers. The drawtube runs on a solid stainless steel rail mounted on the side. Additional stabilisation is provided by ball bearings on the sides. The focuser can easily carry heavy accessories weighing more than 5 kg and it does not tilt when the position is fixed.
The advantages of the 3" Linear Power focuser at a glance: New drawtube with steel sheet held by four large bearings makes focusing smoother than ever The smooth focus motion and 11:1 fine focus wheel allows precision adjustment and critical focusing of eyepieces & cameras 360° rotation system before the focuser and before the 2" receptacle 2" and 1.25" adapters with solid compression ring clamping Excellent illumination even for large camera chipsFlatteners and correctors for astrophotography
We suggest following correctors:
2" Flattener for cameras to APS-C size sensors - suggested distance from M48 connection thread to camera sensor 109 mm
for full size sensors - suggested distance 91 mm from M69 connection thread to the camera sensor
Photoline 2" 0.79x Reducer und Correctorreduces the focal length from 840 mm to 663 mm and increases the f/ratio from f7 to f5.53
