Telescope accessories Capacity Type

Describes the type of accessory in more detail.

More information:

  • Aluminium dew shield cap
    Protects the front surface of the telescope from condensation.
  • Amici prism
    A prism at 45° or 90°, which produces an upright and right-sided image for refractor, SC, and Mak telescopes.
  • Barlow lens
    Extends the focal length and thus increases the magnification of a telescope. Is seated between the telescope and eyepiece or camera.
  • Broadband filter
    Nebula filters that allow a very wide range of the spectrum through, but block stray light and certain wavelengths associated with artificial (neon) light. They are also used for photography at dark sky sites.
  • Colour filters
    Colour filters are used for observing planets. Surface details, bands of clouds and other phenomena become more easily visible.
  • Diagonal mirror
    A deflecting mirror connected to a focuser, which deflects the image upwards by 90°. This makes observing more comfortable.
  • Erecting lens
    An erecting lens corrects the image for nature observing and extends the focal length by a small amount.
  • Filter wheel
    A filter wheel provides space for several filters, which can be easily selected via a rotary function. This eliminates the need for time consuming filter changes.
  • Focal reducer
    Reduces the focal length of the telescope.
  • Interferential filter
    Filters light through thin layers and allows it to pass only at certain wavelengths.
  • Laser pointers
    A Laser Collimator is a tool that helps align the optical axes of the mirrors
  • Moon filter
    A moon filter reduces the bright light of the moon and protects against glare.
  • OIII filter
    A nebula filter for larger telescopes and as a supplement to the UHC filter. OIII filters are suitable for planetary nebulae and supernova remnants.
  • Polarising filter
    Linear polarising filters reduce the light and let it through in one direction only, for example vertically. Double polarising filters can be rotated against one other. As a result, the filter can be infinitely adjusted from light to dark.
  • Solar prism
    The Herschel wedge deflects 96% of the sunlight away from the light path and allows only 4% of the light to pass through. Additionally, an ND3 grey filter, a UV/IR blocking filter and a solar continuum filter are also required for observing.
  • T Adapter
    An adapter with an integrated T2 thread. This is a standard thread for which there are many appropriate accessories.
  • UHC Filter
    A nebula filter is mainly suitable for visual observing and for smaller telescopes. It increases the visibility of hydrogen bands and planetary nebulae.
  • USB filter wheel
    A filter wheel that can be connected to a PC via USB and controlled electronically.
