Skywatcher Esprit-150ED 150 mm f/7 FPL53 Triplet APO Telescope OTA

Skywatcher ESPRIT 150 ED Professional FPL53 Triplet Apo

Skwatcher´s largest apochromat, like the other ESPRIT apochromats, was designed for demanding astrophotography. The very well corrected objective offers a high contrast image, free from disturbing chromatic aberrations. Good solid mechanics, such as a stable 3" Linear Power focuser, complement the optics and make the instrument a very good all-around telescope.

The objective of the ED150:

The triplet objective consists of an FPL53 APO element from Ohara and two additional glasses from SCHOTT, a very well-known glass manufacturer. The three air-spaced lenses are mounted in a stable cell and are also held stable for adjustment. The objective is of course adjustable.

The 3" Linear Power focuser:

This focuser is superior to conventional Crayford focusers. The draw tube runs on a solid stainless steel rail mounted on the side. Additional stabilization is provided by lateral ball bearings. The focuser carries even heavy accessories over 5 kg without any problems and it does not tilt when locking the position. The main features are:

♦ Laterally mounted stainless steel running surface
♦ Dual speed for precise focusing
♦ 360° rotation capability
♦ 2" and 1.25" connection, as well as M74x1 and M86x1 male threads for screw adaptations

Suitable correctors for astrophotography

♦ Skywatcher offers two correctors for the ESPRIT 150ED that screw directly to the focuser. The # 20190 is a 1.0x corrector that does not change the focal length. The # 20096 reduces the focal length by a factor of 0.77x. Both correctors have the M48 connection thread on the camera side and have 55 mm working distance to the sensor.

♦ With suitable adapters, you can adapt to the M68x1 female thread and can also attach other correctors, such as the TSRED379, a 3-element 0.79 reducer and corrector, or the professional TSFLAT2.5, a 1.0x corrector with long working distance for individual adaptations.

All adapters and correctors are linked in the accessories section.
