Venus--just like the moon, Venus changed phases from month to month. Some views of brilliant Venus appear as if you were looking at a distant crescent moon.

Nebulae--The Great Orion Nebula is a very well known night sky object. This and many others are brought to you by this telescope.

Star Clusters--View millions of stars densely packed in a cluster that resembles a ball.

Galaxies--One of the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. Enjoy this and many others.

Much, much, more!

ANSWERS TO COMMONLY ASKED QUESTIONS

1.

The image I see in the telescope is upside down

An upside-down and reversed image is a

 

and reversed from right to left?

common characteristic of most astronomical

 

 

telescopes. Try using the enclosed erecting

 

 

eyepiece and penta mirror to remedy this

 

 

problem.

 

 

 

2.

How do I determine the power my telescope?

The power of your telescope can be determined

 

 

by dividing the focal length of the objective lens

 

 

by the focal length of the eyepiece. The

 

 

eyepiece focal length is the number printed on

 

 

the eyepiece. (For example: 1000 ÷ 25 = 40X)

 

 

 

3.

Where do I find the Telescope Focal Length

The telescope focal length is the same focal

 

 

length as the objective focal length. For this

 

 

telescope it is 750mm. Telescope focal lengths

 

 

range from 600mm to 900mm on Bushnell

 

 

Telescopes.

 

 

 

4.

What can I see with my telescope?

Telescopes with power ranging from 25X to 50X

 

 

can be used to view Star Clusters and Nebulae.

 

 

90X to 120X telescopes can view galaxies. Most

 

 

planets can be seen at 150X and higher.

 

 

 

5.

What do the numbers on the eyepiece mean?

The numbers on the eyepiece represents the

 

 

“focal length” of the eyepiece.
