Manual: Baader Planetarium TriBand-SCT
1
Installing the TriBand
The telescope is connected to the mount like any other telescope via the 3"/CGE
dovetail bar. Please note that the 3" Celestron CGE bar is not identical to the 3" Los-
mandy standard, but is compatible with the 3" clamp of most mounts. If your mount
can only accept dovetail bars with the Losmandy standard, you can use one of the
following dovetail bars:
• Baader Planetarium Dovetail Bar 3", 470 mm for Celestron
# 1501615
• Baader Planetarium Dovetail Bar 3", 530 mm for Celestron
# 1501620
Both bars fit for TriBand C8, C9
¼
and C11. The longer bars protrude slightly at the
back of the C8 to help balance the telescope when attaching accessories such as
heavy cameras or a long H-alpha filter with a telecentric system. You may need to
remove the telescope's carrying handle for installing the bar.
For the Triband C8, you can also use
• Baader V-Dovetail Celestron-orange anodized, 345 mm für 8" SC/HD
# 2451734
to use the telescope on mounts with Vixen-style clamps
Longer rails with matching holes are possible as custom-made products.
Attaching accessories
The telescope has got a 2" adapter thread (SC-thread). The Celestron Standard Visual
Back for connecting 1.25" accessories is screwed onto it. The TriBand 11" also has a
3.3" adapter thread.
The 2" SC thread allows you to connect heavy accessories tightly and tilt-proof. For
the adaptation of accessories with T-2 thread please use
• Baader SC / HD Ultra Short T-Adaptor, 9 mm optical length
# 2958500B
For accessories with the standard 2" nose piece, you can install the 2"-SC-Clicklock
eyepiece clamp
# 2956220
at the telescope. This eyepiece clamp fits to all three
telescopes. For the 11" model, you can alternatively use the SCL clicklock
# 295623
,
which fits the 3.3" thread and allows maximum light transmission.
Focussing
To focus the telescope, simply turn the focusing knob
1
at the back of the telescope. Counterclockwise rotation
focuses on more distant objects, clockwise rotation on
closer ones.
As with all telescopes with main mirror focusing, slight
mirror tilting may occur when you change the focusing
direction (see also page 17/18). Get into the habit of always
focusing anti-clockwise last, then the mirror will be clam-
ped sliding on its guide tube and the collimation will also be
maintained.
Tip:
Especially for photography, use a motor focuser such as the Celestron Focusing
Motor
# 821160
to focus vibration-free from your PC or via a Celestron mount with
Nexstar hand controller.
