Sky-Watcher Esprit 100ED Pro apochromatic refractor telescope with AZEQ6.
Large refractor telescopes are a dream for many people who want to obtain impressive planetary observations as well as inspiring deep sky images. The absence of central obstruction, the resulting image sharpness and the significant field of view, attract more and more of the amateur astronomy community to this optical configuration, valid for both observing and astrophotography.
To satisfy the most demanding users this new product line includes a high quality ED triplet. With an Ohara FPL-53 center element and two Schott lenses, Sky-Watcher has turned to the high quality of the Esprit to deliver high optical performance in planetary and deep sky imaging.
Designed for the advanced amateur astronomer, with its unique three-lens air-spaced design, chromatism is completely under control, image delivery is spectacular thanks to exceptional contrast.
The field corrector with two 48 mm lenses offers a perfectly flat field with a diameter of 44 mm. Its oversized lenses offer a wider and clearer aperture and have no internal reflection.
With this equipment you can enjoy the giants Jupiter and Saturn as never before, rediscover the Moon, and with its large diameter, you can photograph the most beautiful nebulae with the stars well spotted even at the edges of the field. With the 100 diameter you won't miss anything in the deep sky (this tube is 2.25 times larger than an 80 mm diameter instrument).
The absence of chromatic aberration, the focal ratio of 5.5 and the field flattener will allow you to obtain amazing results with an APS-C format sensor.
The telescope mounts a Crayford dual-speed 01:10 linear power focuser. To exploit this focuser to the fullest Sky-Watcher has designed a new 3'' eyepiece of patented design. The focuser is of CNC construction and its 01:11 development is smooth and precise, indispensable for obtaining a sharp image at high magnifications in visual or astronomical photography. The eyepiece holder is rotatable, which will greatly facilitate framing to give your shots a unique touch.
The optical tube is machined from aluminum, with retractable spray shield to make it more compact, and the interior is specially designed to reduce stray light. As a high quality detail, the lenses have a very high light transmission rate thanks to several metal deposits.

AZEQ6 mount.
The new SKYWATCHER AZ-EQ6 SYNSCAN mount offers optimum stability and pointing precision for a wide range of heavy professional photographic and video equipment. It is a hybrid mount with the possibility to work in Altazimuthal format for general use and also in Equatorial format for astrophotography. The SKYWATCHER AZ-EQ6 SYNSCAN mount is supplied with the SYNSCAN control knob that includes dual firmware for both AZ and EQ formats. It can track and locate more than 42,900 celestial objects stored in its database.
The SKYWATCHER AZ-EQ6 SYNSCAN mount is capable of carrying heavy professional photography or video equipment. It is also a very easy to transport and efficient mount because it weighs only 15Kg and has a load capacity of 25Kg (excluding counterweight).
Tracking made easy -- Freedom Find™.
With the patented FREEDOM FIND (dual-encoder) technology, the telescope can be moved either manually or electronically on both axes without losing position or alignment information. After moving to a new object, the telescope will automatically start tracking the new object precisely. There will be no need to re-align the telescope during the entire observing session. This technological feature we value very positively from Telescopiomania as it incorporates a functionality that until now was only available to users with professional mounts.
New features:
-
-
-
-
- German Equatorial/Altacimutal dual mode mount.
- Permanent Periodic Error Correction (PPEC). PPEC can be calibrated with an Autoguider or via PC.
- Improved and more reliable power connector.
- Encoder on both axes allows the position of the mount to be known at all times. Users can disengage and move the mount without losing the correct alignment of the mount.
The best innovations according to Telescopiomania:
-
-
-
-
- Belt-driven displacement of the axes.
- Very smooth movement minimizing the Periodic Error.
- Practically no backlash.
- Quieter than other mounts in its class.
- Programmable shutter control for DSLR cameras.
- Motor controller board that offers greater torque and precision.
- Mount head prepared to accept VIXEN and LOSMANDY type dovetails (45/75mm)
- Illuminated polar finder is included as standard.
Also featured:
-
-
-
-
- Motion resolution: approximately 0.14 arc seconds.
- Includes electronic shutter control port for DSLR.
- Autoguiding port.
- PEC control in EQ mode.
- Polar alignment facilitated by the included illuminated polar finder.
- Alignment methods: 1, 2 or 3 stars (EQ) / alignment to 2 stars or brightest star (AZ)
- Connection to the telescope: 2 clamps are supplied that accept VIXEN and LOSMANDY type dovetails.
- AR/DEC crowns: D=92.5mm, 180 teeth, made of brass.
- AR/DEC shafts: D=40mm, made of steel.
- Latitude adjustment range: 10º to 70º (EQ), 90º (AZ)
- Azimuth adjustment range: about ± 9º
Special applications of NEQ6 PRO and AZEQ6 PRO mounts:
Telescopiomania would like to emphasize that the SKYWATCHER NEQ6 PRO and AZEQ6 PRO mounts are not simple GOTO mounts whose application is reduced to the astronomical field. Some customers also use GOTO mounts of this type as a stable and precise platform to perform specific positioning or to follow the rotational movement of the Earth (installation of solar panels, oil extraction platforms, etc).
