TS Eyepiece Expanse 5 mm Wide Angle 1.25 and 2''  connection

Excellent Image Quality up to the Periphery:

TS Expanse eyepieces were designed for excellent image quality throughout the large field of view. Even with fast Newtonian telescopes the image will remain crisp up to the periphery. The TS Expanse eyepieces offer excellent value for money.

Digiscoping / Photography:
In addition to their superb visual performance the Hyperions are also ideally suited for photography. Their integrated M43 thread are the basis for a rigid adaptation of your DSLR camera or compact digital camera.

1.25" and 2" Telescope Adaptation:
Optically the Expanse are 1.25" eyepieces. For a more solid grip you may choose to attach them to a 2" focuser. The eyepiece body has an integrated 2" barrel with safety undercut in addition to the 1.25" barrel. Using this barrel will move the eyepiece a few centimetres closer to the telescope, which might be important when on use in a telescope with a tight back focus distance.

Specifications and Features for Visual use:

  • With 70° Apparent Field of view the Expanse are true wide angle eyepieces. They offer a crisp image up to the periphery and a long eye relief for comfortable viewing.
  • Superb Image Sharpness - The intricate optical layout of the Expanse eyepieces results in an excellent image sharpness both on the optical axis and up to the periphery of the large field of view. Even in very fast Newtonians down to f/4 there will be only a very moderate degradation in sharpness towards the edge. This is particularly important for Dobsonian telescopes where a larger useful field of view effectively means that higher magnifications can be used successfully!
  • Expanse Eyepieces offers High Transmission and Contrast, they feature an excellent multicoating on all glass-to-air surfaces. The lens edges are carefully blackened.
  • No Kidney Beaning Effect because Expanse eyepieces have oversized lenses.
  • No Vignetting - The large lenses offer a constantly illuminated field of view. In many simpler eyepieces you will notice a degradation of the image brightness towards the edge of the field of view.

TS Expanse Eyepieces are ideally suited for Photography:

TS Expanse eyepieces come with an integrated M43x0.75 thread. Just screw off the rubber eyeguard and attach the (optional) Hyp-T2 adapter. Now you have a solid screwed connection to T2 rings for your SLR camera or adapter rings for compact models. No tilting or off-axis problems any more!
Easy adaption of DSLR cameras

  • Easy adaption to spotting scopes for photography
  • No vignetting through the oversized lenses
