Omegon f/4 Astrograph: For unforgettable astrophotography
Which telescope delivers beautiful images with as little effort as possible? With an Omegon Astrograph, this is easier than with conventional telescopes. Why? The answer is obvious: because an aperture ratio of f/4 means plenty of light intensity and yet short exposure times. Immerse yourself in the world of deep sky photography. Marvel at faint galaxies or countless details in hydrogen nebulae. The Omegon Astrograph sets a new standard for your astrophotography...
The advantages at a glance:
- Astrograph f/4: telescope with ultra-fast aperture ratio for short exposure times
- Short overall length, also suitable for medium-sized mounts
- Large image field for extended objects: approx. 24 mm illumination
- Parabolic primary mirror with 94% mirror coating for bright images
- Large secondary mirror: good illumination for DSLR cameras
- Stable 2" eyepiece focuser with 1:10 reduction and 1.25" reduction
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.
