Περιγραφή
The Photon series of Newtonian telescopes from TS Optics are ideal for a cost-conscious introduction to astrophotography. The large aperture ratio has a very positive effect on the exposure time required. The high-quality focuser helps with focusing.
However, these telescopes are also very well suited to purely visual observation and are supplied with an extension sleeve to focus with the eyepiece.
These Newtonian telescopes are real all-rounders!
This Newtonian offers top performance for observation and photography:
- The contrast with the moon and planets is very good. The image and resolution of the moon and planets is equivalent to that of a high-quality 4″ apochromatic refractor – for a fraction of the price.
- Nebulae and galaxies are already visible with fine structures. The 150 mm aperture provides you with about twice as much light as a 114 mm aperture. With a 2″ overview eyepiece, you can observe a field that is about 5 times as large as the full moon. This makes the Newton a real comet finder and large-field telescope.
- The f/6 focal ratio also makes the telescope well suited for astrophotography. Smaller chips even work without a coma corrector. We have suitable coma correctors in our range for medium or larger CCD and DSLR cameras.
The 2″ Crayford focuser: Simpler Newtonian telescopes have a 1.25″ focuser – sometimes not even made of metal. This focuser is, of course, made of metal. The focuser tube is ball-bearing mounted. Even heavy cameras and eyepieces are carried without any problems and sensitive focusing is still possible. The focuser is supplied with a reduction to 1.25″. The 1.25″ and 2″ accessories are clamped gently and securely by a ring clamp.
The focus position has been optimised for photographic work, so a 35 mm extension is required for visual use. Our recommended accessories include one for 1.25″ and one for 2″ plug-in dimensions.
