Omegon 110mm apochromat - more light for beautiful astronomy photos

Omegon's new apochromat now provides you with even more light. Its 110mm aperture shows more detail for even better astronomy photos. Compared to its predecessor, it offers you 20% more area, but still remains compact. Let yourself be inspired - by brighter and more brilliant pictures.

The advantages in a nutshell:

  • all optical surfaces multi-coated
  • refined baffle system to prevent reflections
  • very high contrast and pin-sharp star images
  • light and robust: telescope tube made from carbon fibre
  • carbon fibre dew shield lined with felt
  • fine focusing: focuser with 1:11 reduction and protective cap

The optics

The Omegon ED apo refractor has outstanding optics, a thoroughly though-out design and high-quality mechanical components. This very special telescope provides astrophotographers, visual observers or nature watchers with a unique source of pleasure when observing starry skies or nature watching. Pin-sharp stars, right out to the edge of the field of view, can be just as taken for granted as the outstanding mechanical precision.

The apochromat doublet

TrueColor lens elements are built into the objective lens of Omegon ED apochromat doublets. The two element objective lens is constructed of a clever combination of OHARA FPL-53 and S-NBM51 glass. These are special types of ED glass with high and low refractive indices and superior light transmission characteristics. A particularly special feature is the use of S-NBM51 glass, which is usually employed in the optics of apochromatic fluorescence imaging microscopes. The benefit to you is that the optics provide a particularly sharp and high-contrast image!

You will be able to see subtle detail on planets, using a Schmidt-Cassegrain telescope for example.

Carbon Fibre Tube

This apochromat is well suitable to visual observing but was, in fact, developed especially for astrophotography. Use the advantages of a carbon fibre tube: it is particularly light and so even perfectly suitable for using on smaller mounts. The tube also offers a very high inherent stability and only minimal thermal expansion. These advantages are particularly useful for astrophotography, as the focus remains stable for the whole night. The dew shield is also carbon fibre and can be extended easily. In addition, the tube is lined with black felt.

The Focuser

The telescope is equipped with a Crayford style focuser. It belongs to a new generation of drawtubes, which are patent pending. Absolute precision and enormous load bearing capacity are the main advantages of this focuser. It can carry accessories of even up to 10kg in weight by the use of an additional locking screw. Even under the application of extreme force, the drawtube will not move even by a millimetre: Once you have found focus, it will not change, even if you move where the telescope points to in the sky.

A 1:11 reduction ratio provides you with fine adjustment when focusing, allowing even more precision than with most telescopes. Do you use a full format chip for astrophotography, or do you intend doing this in the future? Even with full format cameras, images of objects are recorded free of vignetting. The complete focuser is freely rotatable: loosen the locking screw and the unit can be rotated through a full 360°.

Carrying case included

The aluminium case provided is ideal for storing your valuable optics. Extremely robust, with carrying handles and metal fittings, it can withstand some shaking around with no problem. The interior features accurately cut out foam mouldings which keep the telescope tube in exactly the same condition as when you last stored it there.
