Field Flattener & Coma Corrector

Product Highlights

  • 7.5" / 190mm Primary Aperture
  • 1000mm Focal Length, f/5.3 Focal Ratio
  • Apochromatic Compound Optical Path
  • 2" Dual-Speed Crayford Focuser
  • 9x50 Right-Angle Erect-Image Finderscope
  • Cradle-Ring Mounting Assembly
  • Vixen-Style Dovetail Plate

Sky-Watcher's 7.5" f/5.3 Maksutov-Newtonian Telescope features a hybrid optical path that combines the parabolic mirror of a Newtonian with the front corrector plate of a Maksutov to create an optic that corrects for spherical and chromatic aberrations, and comas across the entire field of view. An added benefit of the front corrector plate is that the secondary mirror can be attached to it, removing the struts and supports found in traditional Newtonians and eliminating the diffraction spikes they cause which can degrade the image. The resulting views through the scope are bright and clear with virtually no distortion across the entire field of view with true color rendition.

The scope is equipped with a 2" Crayford-style focuser, instead of the more common rack-and-pinion, which uses a steel rod held tightly against the drawtube to provide a toothless friction system that eliminates backlash and enables ultra-fine, precision focusing with its 10:1 reduction micro-focusing knob. Employing a 2" drawtube allows the use of larger eyepieces and accessories.

While there is no mount included, a cradle-ring assembly is provided. It clamps over the optical tube and lets the user adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balancing, while avoiding interference with other equipment. A stainless steel Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle, and a 1/4"-20 stud on the top of the cradle ring assembly enables a camera to be piggybacked onto the scope for wide-field photography.

Optical Performance
  • 7.5" (190mm) aperture
  • f/5.3 focal ratio
  • 1000mm focal length
  • Pyrex optical parabolic primary mirror further corrects spherical aberration
  • Front corrector plate corrects spherical and chromatic aberrations, and comas (off-axis aberration) across the entire field of view
  • Secondary mirror attached to corrector plate to eliminate diffraction
  • Internal baffling reduces stray or unfocused light for bright and clearer images
  • High-quality Schott optical glass elements
Mounting
  • Requires user-supplied mount and tripod
  • Cradle-ring assembly enables adjustment to the OTA orientation relative to mount
  • Vixen-style dovetail plate
  • Integrated 1/4"-20 piggyback camera mounting screw
Focuser
  • Dual-speed Crayford-style
  • 2" diameter drawtube to accept larger eyepieces
  • Coarse-focus knob, 10:1 fine-focus knob
  • Crayford focusers use a toothless friction system that allows for super-fine precision focusing without backlash
  • Brass compression ring to protect eyepieces and accessories
Optical Accessories
  • 9x50 right angle erect-image finderscope
  • 42mm T-ring adapter to mount user-supplied DSLR camera, requires camera specific adapter

Sky-Watcher SynScan mounts have been designed for use by novices and experts alike. These mounts provide extremely high precision tracking and have built in autoguider ports. Even the most demanding experts will be impressed by the capability of these mounts for astrophotography.

For novice users the user-friendly menu allows automatic slewing to over 13,400 objects. Even an inexperienced astronomer can master its variety of features in a few observing sessions. The SynScan Hand Control also has the ability to connect to a computer via a RS-232 cable. Once the connection has been established between the computer and SynScan Hand Control, many commercially available planetarium software programs can be used to control the EQ6 PRO Mounts, They also come with features that advanced astronomers can appreciate:

• Positioning Accuracy up to 1 arc minute. Accuracy enhanced by software collimation error (mount mechanical error) compensation.
• Stepper motors with 1.8° step angle and 64 micro steps driven.
• Slewing speed up to 3.4°/sec (800X).
• Auto Guider Interface for astro-photography.
• Guiding speed selectable from 0.25X, 0.50X, 0.75X, or 1X.
• Object database containing complete Messier, NGC, and IC catalogues.
• Minimal vibration for steady long-exposure photography.
• Periodic Error Correction.
• PC compatibility.
• Upgradeable hand control via internet download.
