Teleskop Service 2" Single Filter Drawer System



The Teleskop Service 2" Single Filter Drawer System is the shortest filter quick changer that we know. It u ses only 15mm optical length! The TS Optics Filter Quick Changer allows you to switch between filters within a few seconds without having to refocus after the filter change!



Visual and Photographical Use:



There are many applications that require you to change between filters regularly. The usual way is to remove the camera or eyepiece from the telescope, unscrew the filter, screw in another filter, put everything back in the telescope and focus again. This procedure is annoyingly bothersome and takes a lot of time!



Examples of Use:

  • Astro Imaging: LRGB colour imaging, narrowband colour imaging, use of different contrast filters and nebula filters
  • Planet Observing: Ideal for using colour filters. The quick change between the filters allows you to directly compare the effect of different filters and thus choose the ideal filter for the particular application.
  • Deep Sky Observing: You can directly compare the impressions with UHC filters, O-III filters and other filters. This allows you to get the most detail out of each object!


Advantages of the Filter Quick Changer in comparison with other systems:
  • there is no limit to the number of different filters you can use.
  • very low profile
  • this also results in best possible field illumination
  • the filter quick changer needs less space than e.g. a filter wheel
  • the filters currently not in use can be stored protected from dew and dust. In classical filter drawers the filters are completely unprotected!



The ultra low profile of the TS Filter Quick Changer results in best possible field illumination. Especially on "fast" telescopes, e.g. some Newtonians, the optical length has a big influence on vignetting! The TS Filter Quick Changer even allows you to use 1.25" filters (with optional adapter) on CCD cameras that would normally require larger filters with other filter holders.

Good but must add 3mm
This is a good solution for situations where the length of the optical train is limited e.g. by the requirement of a reducer/corrector. TheTS OAGs are designed in such a way that the square filter drawer system can directly be screwed on them.
But the wall thickness and hence the telescope side length of the female T2-thread of the filter drawer holder is 2mm. The length of the male thread on TSOAG27 is 5mm. Hence a 3mm spacer needs to be inserted making the total optical length of the filter system 18mm. Without the spacer the male thread protrudes inside of the drawer housing and prevents the drawer from being removed.

There is a drawer for 50-50.8mm filters available in Europe.  Is it available in the U.S., or will this 2" drawer hold 50mm unmounted filters?
