The Earth's atmosphere can sometimes cause a distortion of the telescope's view. At low power, the effect may be unnoticeable. But at high power, it can result in a badly blurred image. The result is an image which is fuzzy, ill-defined, and poorly resolved, through no fault of the telescope. The best advice when viewing any object is always start out at the lowest power and, by exchanging eyepieces, gradually build up to higher magnifications until the object is best seen.
All lenses produce images that are upside down.
To flip the telescope image around requires certain lenses or prisms which absorb and scatter the light the telescope has collected. An erecting prism between the scope and the eyepiece can be used to rotate the image. This is especially useful when one wishes to use the telescope for terrestrial viewing. There are plenty of optional accessories and equipment which can be acquired to enhance the power and utility of your telescope. We offer an array of accessories to better enhance viewing including filters, barlow lenses, plossls, astrophotography accessories, camera adapters and erecting prisms.
