1. I can't see anything when I look through my telescope
The telescope is only suitable for astronomical observing and when used outside at night. Observing from
inside the house or during the day is not usually possible.
The dust caps must first be removed and an eyepiece inserted before you can start observing. Are you
sure you have you removed all the dust caps, not just the small ones? If you have not, then no light will
enter the telescope and everything will appear black.
2. I cannot locate any objects
Objects visible in the finder scope will not necessarily also be visible in the main telescope just after you
have assembled the telescope. The main telescope and finder scope must first be aligned with each other!
Insert the eyepiece with the longest focal length (20mm or 25mm) into the focuser and move the tele
scope along the horizon until you can see some prominent object through it. A distant chimney or a
church tower is ideal. This object can then be used to align the finder scope by using the adjusting
screws on the side of the finder until the object is centred in both scopes.
3. Objects are not in focus
Are you sure that you have focused the object properly at the focuser? Always start off with a low
magnification (longer focal length eyepiece), focus the image and then increase the magnification
step-by-step. Using a high magnification right from the start is not a good idea.
Is the telescope well collimated? Mirror collimation can shift due to knocks during transportation. If it is too
badly out of collimation, the telescope will produce a poor quality image at higher magnifications.
Have you allowed the telescope to cool down for a sufficient length of time outside? The mirrors and tube
must adapt to the ambient temperature (acclimatize), or the instrument will not provide a good image.
Is the magnification you are using too high for the object concerned? If you are trying to observe a faint
galaxy at 300x magnification, for example, it is almost certain that no object will be seen in the image.
Every object has its own optimum magnification. Use a lower magnification and try again. Try out your
telescope on the moon. It is the brightest available suitable object and is perfect for trying out all the
different magnifications.
Note: Stars do not look any different at higher magnifications than they do at lower magnifications. It is
objects such as planets and nebulae where magnification is of interest.
4. I only see my own eye when I look through the telescope
If you have forgotten to insert an eyepiece, you will only be able to see your own mirror image. You will
only be able to see a proper image after you have inserted an eyepiece. Please insert the eyepiece with the
longest focal length (e.g. the 25mm eyepiece) first.
