6. Troubleshooting and frequently asked questions
Q: I can’t get to focus my telescope, only get a bright circle.
R: Make sure you have inserted the Diagonal and an eyepiece (start by the lowest power eyepiece –
H20). Point to a distant object during the day and proceed as described in 4.
Q: I get a mirrored view of the objects. Like if they were reversed, and
R
show up like
ᴙ
R: This is caused by the Diagonal Mirror. It has a mirror inside. To get a corrected image it is
necessary to use the Erecting Lens and the Eyepiece as shown below.
Q: When I use the barlow lens and the H6 eyepiece the image is so dark I can’t hardly see anything.
A: Power should be used with moderation. It depends on how stable the atmosphere is, too much

Q: Is my telescope compatible with other eyepieces ?
A: Omegontelescopes are compatible with all telescope eyepieces from different manufacturers as

a fellow astronomer go ahead. Different eyepieces provide different visual experiences.
Q: I want to use my telescope to take pictures
A: This telescope is designed for visual use. It doesn’t mean it can’t be used for photography, however
it will be hard to get high quality pictures with this telescope. If you have a smartphone you can shoot
the Moon or some terrestrial objects. Search online for digiscoping and afocal photography.
Q: The stars only appear as points in the telescope
A: Stars will always appear only as points, even in the largest telescopes in the world. It is more
interesting for beginners to observe two-dimensional objects, such the moon or planets. Once you
find these, you will be able to start learning about the astronomical calendar.
Q: I would like to observe the Sun
A: An appropriate solar filter, placed over the objective, is essential for observing the sun. These are
