Warning notes
  • General safety instructions DANGER Risk of suffocation! Improper use of this product can result in suffocation, especially for children. Therefore, carefully observe the following safety instructions. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! Keep cords, ribbons, and similar materials away from children! They could accidentally strangle themselves and suffocate! NOTE Risk of material damage! Improper handling can damage the device and/or accessories. Therefore, only use the device according to the following safety instructions. Do not dismantle the device! In the case of a defect, contact your dealer. They will contact the service center and may send the device in for repair.
  • Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
  • Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
  • Do not expose the device to high temperatures.

Vixen 1.25”/ 31.7 mm Star Diagonal
This Vixen 90° mirrored Star Diagonal, with 1.25” / 31.7 mm nosepiece connection, makes observing objects higher up in the sky much more pleasant and also allows the user to revolve an eyepiece to a more comfortable observing position. This star diagonal is a good quality option and compatible with a large array of refractors and Cassegrain design instruments. It will accept 1.25” / 31.7mm eyepieces and accessories and also has a threaded nosepiece, into which can be fitted 1.25” filters, or Barlow elements, saving you the bother of having to keep swapping these when using different eyepieces. The inside of the diagonal is blackened to minimise internal reflections and light scatter and the body has a pleasingly well-engineered feel to it, without being too weighty. Eyepieces and other accessories are held in place by a simple-to-operate knurled set screw. As this is a mirrored diagonal, it also corrects the up/down orientation of image in astronomical refractors and Cassegrain telescopes, but please note that left and right will still be inverted within the field of view. Not suitable for use with Newtonian telescopes.
