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.
- exclusive 2" Crayford focuser with stainless steel ball bearings
- indestructible - stainless steel system for durability
- precision focus via 1:10 reduction ratio
- high load capacity for any accessory - even with an open clamp
- simple to connect to Skywatcher telescopes via an adapter
- anti-reflection ridging - for good contrast
Perhaps you already own a telescope with a rather basic focuser? Note how its operation lets the ball bearings dig into the soft aluminium of the inner tube, scoring it. Do you really think such a focuser will give you a lifetime of good service? If you are one of those people who appreciate accuracy and precision, then you will not be happy with this kind of focuser. It is high time for an upgrade.
