Omegon Telescope Pro Astrograph 154600 HEQ-5

The 154/600mm astrograph on a Skywatcher HEQ-5 Pro GoTo mount – for taking a giant leap with your astrophotography. A very stable and high-precision mount for the OTA, with the option of adding auto-guiding. Take wonderful astronomy photos in future – using the right equipment brings success.

Omegon f/4 astrograph – for unforgettable astronomy photos
Which other type of telescope can be used to create a beautiful image with so little effort? With Omegon astrographs this is easier than with ‘ordinary’ telescopes. Why? The answer is obvious – because an aperture ratio of f/4 means a big light output and consequently shorter exposure times. Immerse yourself in the world of deep sky photography. Admire faint galaxies or details in hydrogen nebulae. The Omegon astrograph sets a new benchmark for your astronomy photos.

The advantages in a nutshell

• f/4 astrograph – a telescope with ultra-fast aperture ratio for short exposures
• suitable to go on medium mountings due to its short overall length
• wide field of view for extended objects – approx. 24mm is illuminated
• 94% reflection parabolic main mirror for bright images
• large secondary mirror – good illumination for DSLR cameras
• robust 2″ Crayford focuser with 1:10 reduction and 1.25″ reducer
• faster cool-down for getting started observing quicker – main mirror fan

94% reflection f/4 main mirror
Astrographs are suitable for visual observing, but only show their full potential when used for astrophotography. Their f/4 aperture means they are among the ‘fastest’ Newtonian telescopes around, allowing you to take shorter exposure images.
The secondary mirror and the parabolic BK7 main mirror are 94% reflective, providing brighter and higher contrast images. One can see a visible improvement when compared to a ‘normal’ mirror which is around 88% reflective.

No shadows, only light – large secondary mirror
Attach your DSLR camera or a modern CCD camera to the telescope and enjoy impressive illumination over a wide field of view. No shadowing is noticeable thanks to the particularly large secondary mirror (see also below). Observing with 2″ wide-field eyepieces is now perfect.

Less mistakes – more fun with the photography
The particularly short OTA length and focal length means the telescope is compact – the astrograph is about 20% shorter as compared to an f/5 system. This means you can also use this OTA’s excellent optics on a medium mount, saving yourself the expense and clumsiness of a heavier mount.
Another advantage is that the astrograph is perfect for extended deep sky objects thanks to its shorter focal length. This system is also more tolerant of small tracking errors than a telescope with a longer focal length. You will achieve some astounding astrophotography with even just a little effort.

2″ Crayford focuser with 1:10 fine focusing
The Omegon V-Power focuser provides precision focusing for all astronomical objects. The 1:10 reduction, sturdy ball-bearings and guide rail make the focuser stable and easy-to-use. Its optimized design means the focuser can safely carry cameras weighing up to 5 kilograms without any slipping.

• extremely precise operation – the ball bearings and stainless steel guide rail mean the focuser tube runs smoothly and precisely
• can carry heavy cameras and eyepieces – no slipping with up to 5kg loads
• 1:10 reduction means precise focusing, includes a focus scale
• anti-reflection baffles for high contrast

• 2″ to 1.25″ reducer

The HEQ-5 Pro GoTo mount:

The high-quality parallactic HEQ-5 Pro GoTo mount turns your telescope into a precision instrument for exciting and fascinating astronomical observing. The extensive equipment included with the HEQ-5 Pro GoTo mount includes a polar finder for easily aligning the telescope to the correct position in the sky, aluminium right ascension and declination scales and electric tracking motors on both axes. So you only need to align the parallactic mount to the celestial North Pole before observing and then let your telescope track via the motors – ideal for getting started in astrophotography! The mount weighs 7.4 kg and is much more stable than the simpler EQ-5 mount. The HEQ-5 Pro GoTo also damps down vibrations much more quickly.
