Tech Talk
Magnification (Power): The magnification of a telescope is determined by dividing its focal length by the focal length of the eyepiece being used. For example, a 500mm telescope with a 5mm eyepiece would magnify objects 100x. Thus, a telescope can provide nearly any magnification required depending on the focal length of the eyepiece used.

Objective Lens Size (or Aperture): The size of the telescope’s objective lens, or aperture, limits the amount of power that can be used effectively. As the magnification of an object increases, the brightness of the image decreases. This is because the light gathered by the telescope is being spread over a larger area.

Reflector: The optical system in a reflector uses a primary mirror to reflect the light from a distant object such that it can be focused to a point and magnified by an eyepiece. Popularized by Sir Isaac Newton in the 17th Century, it is sometimes referred to as a Newtonian reflector.

Focal Length: The measured light path of the optical system (tube length), typically measured in millimeters.

"Go To" Computerized Star Locator: Utilizes an on-board computer to find over 20,000 astronomical objects. Educational descriptions of the objects are provided at the touch of a button. Plus "go to" advanced motorized technology, where the computer automatically finds and follows any object from its 20,000 object database.

3.0 out of 5 stars Bushell North Star, December 29, 2002

I recieved this for Christmas. I returned it the next day because the clip on the leg was broken. The new one was fine until I put it up and the clip broke. I am a photographer and know how a tripod works! I called Bushell and they stated "some got through our quality control" and said they will send out a new, improved tripod; however could not even estimate when it would arrive since they were completely out at the warehouse. When I went to put it away, the middle plastic support broke. From the brief momement I had with it (when it wasn't falling apart) the scope and locater worked. Note that although there is a "lifetime warrantee" on workmanship, the electronics has only a 1-year warrantee (see the fine print). I am a bit hesitant on trusting the mechanics on something that fell apart in my hands-"what's next" comes to mind.

This unit comes w/20,000 preprogramed objects in the sky but viewing them is not particularly easy due to poor lens quality.The motors sound like a flock of screaming banshees,but they will line up the preprogramed objects w/precision.I've had no trouble with the tripod.I notice the instuction book does not mention why there are two telephone type jacks on the remote.If I had payed for this unit myself I would have returned it.
