Question about Bushnell 3" Reflector Telescope w/Talking Guideand Tripod
I suggest that you try the telescope first in daylight (NOT pointed at or near the Sun), using the least powerful eyepiece (the one with the largest number). Try it on objects on the horizon, remembering that they will appear upside down. This is a good time to get the accessory viewfinder scope lined up with the main scope, too. It is unlikely that the finder scope will be much use in pointing the
telescope until you adjust it to precisely line up with the main scope.
When you have become familiar with the low power eyepiece, try a higher power, which will focus at a different point (and be harder to find objects with). Then try it out at night, on a bright, easily found object like the moon.
The higher the power of eyepiece on a telescope, the dimmer the image, the more difficult to aim it at any chosen object, and the more difficult to focus. Do not use the Barlow lens if one came with the scope. There is a very wide range of movement in the focus mechanism, because different eyepieces focus at different points, but the actual focus range for any eyepiece will be a small part of the overall range afforded by the focusing mount. You will also find the the object you are looking at swims out of the viewing field, and you must continually move the scope to follow it. This will be more pronounced at higher magnifications.
