Optical Design
Newtonian
The optical design of a telescope is a feature that defines what sort of observing the telescope is suitable for.
Optical Diameter
130mm (5")
The aperture (diameter) of a telescope’s main lens or mirror. This describes how much light a telescope can grasp.
Focal Length
650mm
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.
F/Ratio
f/5
The relationship between the focal length and the aperture, larger f/numbers imply higher magnification.
Secondary Mirror Diameter
39.8mm
Bounces the light back to the primary mirror and through a hole in its center.
Obstruction
30.6%
The secondary mirror in optical systems creates a shadow, which reduces the contrast and effective aperture performance.
Diameter
Helical 1.25"
Stellar Limit Magnitude
13.6 magnitude
The magnitude of the faintest object visible under zero light pollution conditions.
Resolving Power
0.92"
The ability to clearly distinguish between two points whose separation is less than the smallest angle that your eye can resolve.
Highest Practical Power
260x
Exceeding the Highest Practical Power will result in a fuzzy image.
Light Gathering Power
345
How much brighter things will appear than what the human eye can see.
Finder Scope
Red Dot
A low powered mini telescope with a wide field of view to assists with locating objects before observe through the main telescope.
