4. Start using your Omegon 150/750 EQ-4 telescope.
Point the telescope to a distant object
during the day. It is important to do this during daylight so that you get familiarized with the
telescope operation. A good target is a church tower, a chimney or a distant mountain peak. Rotate
the focuser knob so that the focuser tube moves in and out. Do this slowly. We suggest that you
start by racking the focuser all the way in and slowly move it out. With the PLössl 25mm eyepiece
you should be able to get a focused image easily.
Make sure to use the locking hand knobs (figure 13) and use the fine adjustment knobs (figure 8) to
point the telescope to an object.
ATTENTION! Never use the altitude and azimuth knobs to point to the
telescope. The altitude knob bears all telescope weight and continuous use
can damage it permanently!
5. The finderscope.
Before we mentioned the finderscope as a valuable tool to point the telescope
at an object. To operate properly, the telescope and the finderscope should be aligned. The image
obtained through the finderscope has a much broader field of view than that of the telescope.
Aligning means matching the telescope image to the image of the center of the finderscope. This
way when looking through the finderscope one knows the telescope is pointing exactly to the same
point, making looking at objects much more easier.
5.2. How to align the finderscope?
You have the house chimney (example mentioned before) centered at the telescope eyepiece field of
view. Now look through the finderscope. The small red dot (recticle) in the center of the finderscope
field of view should match the center of the telescope field of view. Adjust the two finderscope
thumbscrews to get the red point to the same object as the telescope (as shown in figure 5.2.2).
