MightyMak 60 & 80
The Omegon® MightyMak 60 & 80 OTA
Congratulations on the purchase of the new Omegon® MightyMak OTA. This telescope will give you
hours of fun, with its all optical glass Maksutov-Cassegrain system. It is the ideal companion to start
in the world of amateur astronomy or birdwatching. With this telescope you will be able to see the
craters on the Moon, star clusters, the Jupiter disc features and its Galilean moons and the rings of
Saturn, but also the beauty of a wild bird’s colourful feathers.

1. Included parts.
We have included several accessories that will make the use of the telescope easier and fun. Please
take a look at the list of parts (below), so you can identify them in the future.
A. Flip-flop dust cap;
B. Amici Prism 90 degrees;
C. 25mm Eyepiece 1.25” (31.75mm); D. Carrying case (not shown);.
E. Mini-tripod (not shown)
2. Getting Started. Start by unpacking the telescope from the
shipping box and remove the protective foil and bubble wrap.
Remove it from the supplied carrying case. Take a look at the tube
and locate the main features. Flip open the plastic dust cap that
protects the telescope’s objective. When not in use, the
telescope’s dust cap should be used to protect the glass lens (#11 meniscus) against dust and fingerprints. Insert the supplied
diagonal (B) in the focuser barrel (#7) and the eyepiece (C) in the
diagonal as shown in figure 1 and 2. We recommend using a finderscope (not included) to help locating your
targets. The recommended solution is a red-dot finder as it is very lightweight and simple to use. The telescope
also needs to be placed on a suitable stable platform such as a photographic tripod or a telescope mount.
Locate one of the two ¼”-20 threads (#12 from tube parts list). Use the one that allows to keep the telescope
balanced on the tripod (complete telescope with accessories). Rotate the hand knob on the tripod to securely
fix the telescope. The telescope is now ready to use.

2.1. Focusing. Focusing is done by rotating the
focus knob (#5 from part list). Targets at infinite (such
as stars, planets or the Moon) require different focus
position than terrestrial objects (which are closer).
Choose one direction and rotate the focus knob to get
a sharp image (focused image). When reaching the
end of the focusing range, the focus knob will become
hard to rotate. Do not force the focus knob as it might
permanently damage the focusing mechanism! Rotate
to the opposite direction, if you are unable to get
Do not force the rotation of the
focus knob as it may cause
permanent damage to the
focusing mechanism!

3. Using the MightyMak for photography. The MightyMak is compatible
with T2 threaded camera rings. Each camera model/manufacturer (E) has a
different connection ring (D). The tube can be used as a high power teleobjective. It can be used with or without a tripod, however, we recommend,
when possible, to use a tripod. The long focal length of the telescope
requires a steady platform to get sharp focused images. The camera’s autofocus settings will be disabled, manual focusing is required and is done with
the focus knob. Afocal photography and other techniques such as projection
photography are also possible. The smartphone photography technique is
also easy to do with this telescope using a suitable smartphone adapter.
4. What can I see with this telescope?
The Moon is one of the most spectular objects to be seen through a
telescope. Even a small telescope will reveal high detail of the Moon’s
surface. You will be able to see the craters on the Moon’s surface and
other features like the Marea. The Moon is a very bright object. It is
better to observe it when the Moon is not full. Try the crescent Moon
and look for features along the terminator (between illuminated and
dark surfaces). Jupiter is the biggest planet of our solar system. It is
also one of the favorite targets for beginners. Galileo was able to
discover that the four tiny dots that circle around the planet were in
fact part of Jupiters system of moons. With this telescope you will not
only be able to see Jupiter’s planet disc with its two major discernible
bands, but also its biggest moons, Io, Europa, Ganymedes and
Callisto. The “lord of the rings” of the night skies, Saturn is by far the
most popular target for small telescopes. Saturn’s rings are discernible even at 60x magnification. In a very
good night you will be able to see the Cassini’s division (the darker band on the Saturn’s rings).
