Baader M68 Tele-Compendium

Telescope connection for Baader FFC and telecentric Systems

Examples of M68 tele-compendium

Telescopes which are used for photography on a professional level need to avoid any deflexure under load. This flexure is is no problem if you observe only visual, but for photography or spectroscopy any deficiencies will make your results unusable. So, you do not only need a sturdy mount with a robust connection to the telescope, but also a very good focusser – with a sturdy connection to equipment like cameras or others sensors, especially if they are used with long accessories like telecentric systems. Usually, these accessories are only attached with a simple plug-in connection. Even with good, self-centering eyepiece-holders with brass clamping ring long accessories can tilt because of the long lever. This tilt will impair professional operation. There is no better adaption than a generously sized screw coupling.

The Baader M68 Tele-Compendium solves this problem. It combines the function of a photographic compendium or matte box, which is a versatile lens hood, with a very sturdy and variable telecope adapter – that's why we have chosen the name Tele-Kompendium. This set is based on the M68-thread which is also used on the large Zeisstelescopes. Because of this, M68 is quite common and perfect for a sturdy connection of optical accessories like the Fluorit Flatfield Converter (FFC) for photographung the planets or a Telecentric System together with H-alphasytems for solar observation.

Connections of the Baader Tele-Compendium

The Tele-Kompendium is screwed onto the telescope. On the telescope side, there are threads for 2,7" (Astro Physics), M68 (Zeiss), M60 (Vixen) and a female M56-thread (Synta). There are optinal adapters for the following systems avaiable:

  • TEC/Feathertouch-focusers
  • Baader 3" Steeltrack- und Hyperion-focusers
  • Pentax-SD-telescopes
  • Takahashi
  • Celestron (3,3"-SC-thread)
  • Zeiss (M68 quick changer)

FFC or Telecentric System are coupled by a T-2-thread at the telescope-side of the Tele-Kompendiums. On the eyepiece side there is the Baader Ultrashort Adapter, which offers a M68-thread as well as standard 2“ eyepiece holder with brass ring and two locking screws to avoid tilting. A 2“/T2 nosepiece is also included – there are many accessories avaiable which use the T-2-thread. Because the 2“-connection is at the far end of the setup, the leverage effect is reduced – and brass clamping ring and two locking screws hold the accessories firmly in place.

The seperate extension tubes enable you to use the system with variable length according to the needs of your setup to achieve the best resultsuse every distance. At the same time, stray light is blocked – no light from the outside can diminish the contrast, and the inside of the telecompendium is carefully blacked.

vielfältige und stabile Nutzungsmöglichkeiten
Der Name gibt es schon her, daß der „T-2 Four-in-One Adapter M68/T-2/M68“ recht vielseitig eingesetzt werden kann. Meinen Hauptzweck erfüllt er tadellos und er macht haptisch einen sehr guten Eindruck. Der Adapter dient bei mir der Aufnahme der Baader ClickLock 1¼" / T-2 Okularklemme (#8) (ohne den Knarrenhebel) und ist mittels M68 Verlängerungsring fernrohrseitig stabil mit dem Teleskop verbunden. Für die Okularprojektionsfotografie dienen dann zur Verlängerung bis zur Kamera zusätzliche M68 Verlängerungsringe.

Das beigefügte Bildmaterial zeigt rot umrandet den 4 in 1 Adapter. Rechts schließt sich die ClickLock 1¼" / T-2 Okularklemme an. Ein Bild zeigt links anschließend (fernrohrseitig) einen M68 Verlängerungsring. (Das blaue Gummiband dient nur dazu, das der Adapter für das Demofoto nicht verkippt.)
