To be able to finally take some good astronomy photos is a dream of many amateur astronomers. If you have some practical experience, then good equipment can do the rest for you. The 8" astrograph collects a lot of light and provides an excellent image. The special construction of the CEM25P GoTo mount makes this telescope easily transportable but nevertheless suitable for superb astronomy photos.
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
Center-balanced Equatorial Mount, whisper quiet and light weight!
The "Z" design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Given its payload capacity, this means the "Z" designed mount is unusually light. A nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft.
The CEM25 is equipped with the latest advanced Go2Nova-technology, making it one of the most powerful and accurate mounts available. Its database includes over 59,000 objects. The Go2Nova-Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects.
Features:
- Specialized astrophotography mount ideal for entry-level and intermediate Astrophotographers
- Spring loaded gear system with customer adjustable loading force
- Gear switches on both R.A. and DEC axes for easy balancing when disengaged
- iOptron AccuAlignTM calibrated polar scope with dark-field illumination and easy polar alignment procedure, allowing for fast and accurate polar alignment
- Polar alignment routine for those who can’t see the Pole Star
- Integrated ST-4 autoguiding port
- Built-in 32-channel Global Positioning System (GPS)
Stepper motor with low power consumption: The mount uses up to 60% less GoTo power consumption then other mounts in category.
