TS Optics TSOAG9 ultra-short off-axis guide for astrophotography
The TSOAG9 short off-axis guide is a development of Teleskop Service. It can be used with almost all telescopes and replaces the telescope guide. The guiding becomes more precise and the mount has to bear less load. The TSOAG9 is the shortest off-axis guide in its class, especially suitable for adaptations where there is little space available. Nevertheless, the TSOAG9 offers convincing features.

The advantages and features of the TSOAG9:

♦ Short design ... only 11.4 mm from the M48 thread to the side connection of the camera.
♦ Better illumination ... 45.5 mm clear aperture; in addition, the prism can be freely adjusted to avoid shadows.
♦ Easy autoguider focusing ... the T2 side connector can also be adjusted, allowing autoguider focusing without changing the distance from the main camera to the corrector.
♦ Three possible positions from the camera to the prism ... due to the special design of the connection adapters to T2, EOS or M48, three positions from the prism to the camera sensor are possible. This also avoids shading of the prism.
♦ Flexible adaptation on the camera side ... in the accessories section, you can find the necessary connection adapters for T2, M42, M48 and EOS. The adapters do not extend the length of the guide off-axis.

Connecting the TSOAG9 to the telescope or corrector:
On the telescope side, the TSOAG9 has a short 2" barrel with a M48x0.75 / 2" filter thread. This allows for flexible adaptation.

Connecting to a 2" receptacle... With the 2" extension ring TSVF230, you can connect the TSOAG9 to any 2" receptacle.

Connection to T2 or M48 threaded correctors ... The TSOAG9 can be directly coupled to correctors or reducers with M48 connection. The TST2-M48s or TST2-M48L adapter allows to couple correctors with T2 connection.

TSOAG9 to the Baader MPCC comma corrector ... The TSOAG9 fits directly into the M48 connection thread of the correctors (left picture). The combination offers coma correction and guidance in a very small space. From the camera connection adapter of the off-axis guide to the sensor, there is 46.6 mm left, enough space even for a DSLR camera.

More connection types ...
Correctors TeleVue via adapter TSTV-M48a
Field correctors Vixen for VMC, VC and APO via adapter TSViRed-M48
Level correctors M68x1 ZEISS via adapter M68I-M48A

How to adapt the imaging camera to the TSOAG9:
For a proper camera connection, you need the optional connection adapter. The adapters are made for the TSOAG9 and match perfectly.

The adapters are conical, ensuring always the optimal position. At the same time, you can disassemble the camera without unscrewing it.

♦ TSOAG9-T2 ... for any other connection via the M42x0.75 / T2 thread
♦ TSOAG9-M42 ... the M42x1 connection is mainly used for a short adaptation of DSLR cameras.
♦ TSOAG9-M48 ... for any other connection via the M48x0.75 / 2 " filter thread
♦ TSOAG9-EOS ... allows the direct connection of Canon EOS DSLR cameras.

TSOAG9G2 - Camera mount with protruding flash housing

The knurled screws of the TSOAG9 collide with the flash housing. If you still want to use the Off-Axis-Guider on a DSLR with a protruding flash housing, we recommend short M4 screws or grub screws. Alternatively, we recommend the TSOAG9EOS for Canon EOS cameras.

Technical specifications:

• Telescope side connection: 2 " body and female thread M48x0.75 length 2.5 mm

• Camera side connection: quick coupling with three screws - diameter 51 mm - fits to the connection adapter
• Side connector for autoguider or cross-guider eyepiece: T2 (M42x0.75) - adjustable distance to the prism
• Clear aperture: D = 45.6 mm
• Distance from prism center to lateral connection T2: 26 mm to 38 mm adjustable
• Distance from the prism center to the front of TSOAG9: 6.7 mm
• Distance from the prism center to the camera side of TSOAG9: 4.5 mm
