4. Start using your Omegon® 76/900 EQ-2 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 PL25mm eyepiece
you should be able to get a focused image easily.
4.1. 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.
4.2. 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 at the center of the finderscope field of view should
match the center of the telescope field of view. Adjust the two finderscope screws to get the cross
pointing to the same object as the telescope (as shown in Figure 4.2.1.).
