Omegon 200/640 astrograph and iOptron CEM40
Large aperture and a high-speed f/3.2 astrophoto system. Using this, you can take short exposure images of objects or capture considerably greater object depth then is possible with many other instruments. The iOptron CEM40 mount perfectly completes the set and, with the integrated iPolar electronic polarscope, you can align your telescope ultra fast.
Omegon 200mm f/3.2 Newtonian Astrograph
The compact and portable Newtonian Astrograph has been developed for the dedicated astrophotographer who wants a powerful telescope with very good sharpness over a large field of view. The Astrograph has been developed for modern sensors with high resolution and large diameters up to full format.
The extremely fast aperture ratio of f/3.2 allows you to take very deep shots of deep-sky objects in just one night, while maintaining very high magnification. Images of extended nebula objects or galaxy clusters are thus possible.
The highlights at a glance:
- Parabolic primary mirror with a 200mm, f/3.2 aperture
- 3" corrector with 0.85 reduction built into the focuser
- 90mm diameter secondary mirror (minor axis) for full illumination up to full format
- Large 3" rack and pinion focuser with reduction and M48 adapter
- Tilting possibility at the focuser
- Adjustable and stable holder for primary mirror and secondary mirror
- Fully illuminated and corrected image field of 44mm diameter
- Working distance of 55mm from the M48x0.75 thread
The mount head weighs only 8.2 kg, yet can support a payload of up to 18 kg. This extremly good payload to weight ratio of 2.5 makes the CEM40 versatile. You can carry it to your favoriert place under a dark sky or at your backyard observatory with a relatively small pier.
But there are more advantages:
- An integrated electronic polar finder scope (iPolar) ensures accurate alignment even at times when the pole star is obscured.
- Large levers on its quick-lock drive engagement system make it easy to snap its gears into place even when wearing gloves.
- There's little chance of your cables getting snagged with the CEM40's internal cable management system.
- The mount comes with the new Universal Self-Centering Saddle for Losmandy and Vixen style dovetails.
- The CNC body looks sharp but is really robust.
The GoTo-Technology features a Go2Nova 8407+ controller with integrated heater for its large display, a 212,000 object library, integrated 32-channel-GPS and ST-4 auto guiding port.
Another great feature besides the center-balance is the ultra-quiet low power consumption stepper motor drive systems. Both models of the CEM40 are precise trackers, the CEM40-EC version delivering <0.25 arcsecond accuracy with its high-resolution encoder and its real time periodic error correction (RPEC).
The CEM40 is a extremly versatile and advanced mount.
