VIEWING THROUGH YOUR
ZHUMELL DOBSONIAN TELESCOPE
Never look at the sun without using a solar filter. Do not use a regular
eyepiece as a solar filter. When using a solar filter, do not remove the
full lenscap, view only through the small opening. Looking at the sun
without proper use of a solar filter can cause permanent eye damage,
included blindness.
When viewing through the telescope, the image will appear to be
upside-down and inverted. This is normal and is a result of the optical
system design. It can be corrected by using an erecting prism when
viewing, but it is not necessary to do so.
Using your finderscope will help you locate celestial much more
quickly as the finderscope is equipped with a wider field of view than
your telescope. To simplify focusing while viewing, start with the lowest
power magnification and work up to the desired power.
When viewing faint deep-sky objects, images will not show color. The
human eye is not able to distinguish the differences in color found in
such dim images. The lack of color is due to human anatomy, not any
limitations of telescope construction.
