Quattro 150P Astrophotography OTA Description
Quattro 150P Astrophotography Reflector OTA
A fast focal ratio of f/3.45
This is especially important for astrophotographers dealing with long exposure times. Imaging telescopes made of less thermally stable material can deviate from optimum focus after long time exposures. It can remain in focus for a longer period of time and long exposure images will stay clear and in focus.
2” Dual-Speed Crayford Power Focuser
The new Crayford power focuser utilises 4 precision ball bearings to support the drawtube and provide great stability and zero image shift while supporting a heavy eyepiece or camera. Moving the drawtube by the roller rather than a rack and pinion ensures exceptionally smooth operation and precise adjustability. The dual-speed feature has a second focus knob that has a 10:1-speed reduction to provide the super-fine adjustments even the most demanding users can appreciate.
Quality Mirror
It features paraboloidal primary mirrors made of Low-Expansion Borosilicate Glass resulting in substantially shorter cooling-down times.
It comes with an impressive 0.5 mm Ultra-Thin Secondary Mirror Support and light gathering power improves greatly.
Optical Design
Reflector
The optical design of a telescope is a feature that defines what sort of observing the telescope is suitable for.
Optical Diameter
150mm
The aperture (diameter) of a telescope’s main lens or mirror. This describes how much light a telescope can grasp.
Focal Length
600mm
The distance that the light has to travel between the aperture and the focal point. A smaller focal lengths will deliver a wider field of view.
Focuser
2″ (50.8mm) Dual-Speed 10:1 Crayford Power Focuser
Wider focusers allow for a wider field of view.
F/Ratio
f/3.45
The relationship between the focal length and the aperture, larger f/numbers imply higher magnification.
Finder Scope
6x30mm
A low powered mini telescope with a wide field of view to assists with locating objects before observe through the main telescope.
Highest Practical Power
300x
Exceeding the Highest Practical Power will result in a fuzzy image.
Tube Weight
5.7kg
You may need a counterweight to prevent your telescope from rotating downwards due to gravity.
