Quick Overview

PlaneWave RC700 f/6.6 Ritchey-Chrétien telescope with Nasmyth focus is a fully automated observatory class telescope with 700mm diameter optical tube and mount. It combines the Ritchey-Chrétien optics by PlaneWave Instruments with a brand new innovative alt/az mount technology that sets a new standard for small observatory telescopes.

Details

The RC700 in its native format (no field flattening lenses) uses only mirror with reflective coatings. This can be useful when making observations primarily on-axis and wide field imaging is not a concern. An alt/az mount is inherently more stable than an equatorial mount since there is no cantilevered mass, nor are there any large protruding counterweights to create a dangerous hazard in a public observatory. An alt/az telescope is also considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. The mass it takes to make a rigid alt/az mount is substantially less, leading to cost savings. Unlike German Equatorial mounts, there are no meridian flips to deal with. You can image from horizon to horizon continuously if desired. Alt/Az is more intuitive to use and no polar alignment is needed. Besides, it is the way the big boys do it!

PlaneWave RC700 f/6.6 Ritchey-Chrétien telescope with Nasmyth focus: main features

Ritchey-Chrétien optical design
Ultra-low thermal expansion fused silica optics
Dual Nasmyth focus, allowing simultaneous mounting of two instruments or easy switching between visual and imaging use
Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
High resolution encoders on each axis for precise positioning
Zero backlash
Zero periodic error
PointXP mount modeling software
Field de-rotator / rotational field framing

Benefits of Nasmyth Focus

The Nasmyth Focus is along the altitude axis so there are virtually no balancing issue as you change out equipment. Eyepieces remain at a constant wheelchair-accessible height, greatly simplifying access to the telescope for public observatories. The rotating tertiary mirror allows you to switch from one Nasmyth port to the other in just seconds, allowing observers to easily transition between imaging and visual use.

Rotating Tertiary Mirror

The RC700 includes an integrated rotator for the tertiary mirror, with magnetic locks to position the mirror precisely for either Nasmyth focus position. The rotator can move from one port to the other in under 10 seconds.

Direct drive motors and encoders

Direct Drive motors mean that there are no gears to cause backlash and periodic error. With high-resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error or have any backlash at all, but the mount will be able to counter against wind gusts. The direct drive motors can move the telescope at incredible speeds for tracking satellites or just to minimize target acquisition time.
