TS Optics TSOAG9 Ultra Short Off-Axis Guide for Astrophotography
The short off-axis guider TSOAG9 was developed by Teleskop Service. It can be used on almost any telescope and replaces the guide scope. Tracking becomes more accurate and the mount is less stressed. The TSOAG9 is the shortest off-axis guider in its class and is particularly suitable for retrofits where space is limited. However, the TSOAG9 offers compelling features.
The advantages and features of the TSOAG9 at a glance:
♦ Short design... from the M48 thread to the camera side connection is only 11.4mm.
♦ The best illumination... the free inner diameter is 45.5 mm; the prism can also be adjusted freely to avoid prism shadow.
♦ Easy autoguider focus... the side T2 accessory can also be adjusted, so the autoguider can be easily focused without changing the distance between the main camera and the corrector.
♦ Three possible positions of the camera to the prism... Due to the special design of the connection adapter in T2, EOS or M48, three positions of the prism to the camera sensor are possible. This also prevents shading by the prism.
♦ Flexible adaptation on the camera side... In the accessories area you will find the necessary connection adapters for T2, M42, M48 and EOS. The adapters do not increase the overall length of the guide off-axis.
Connecting the TSOAG9 to the telescope or corrector:
The TSOAG9 has a short 2" fitting with an M48x0.75/2" filter thread on the telescope side. This allows flexible adaptation.
Connection to 2" receptacle... With the TSVF230 2" extension sleeve you can adapt the TSOAG9 to any 2" receptacle.
Connection to correctors with T2 or M48 thread... The TSOAG9 can be directly adapted to correctors and focal length reducers with M48 connection. The TST2-M48s or TST2-M48L adapter allows adaptation to correctors with T2 connection.
TSOAG9 to Baader MPCC Coma Corrector... The TSOAG9 fits directly into the M48 connection thread of the corrector (image on the left). The combination offers comma correction and tracking in the smallest spaces. From the off-axis guide camera connection adapter to the sensor, you still have 46.6mm, enough space even for a DSLR camera.
More connection options...
TeleVue correctors via TSTV-M48a adapter
Vixen field correctors for VMC, VC and APO via TSViRed-M48 adapter
ZEISS M68x1 level connectors via M68I-M48A adapter
How do I adapt the recording camera to the TSOAG9:
You need one of the optional connection adapters for the correct camera connection. The adapters are made for the TSOAG9 and fit perfectly.
The adapters are tapered, so an optimal position is always guaranteed. At the same time, you can detach the camera without unscrewing it.
♦ TSOAG9-T2 ... for all other connections via thread M42x0.75/T2
♦ TSOAG9-M42 ... the M42x1 connection is mainly used for a short adaptation of DSLR cameras.
♦ TSOAG9-M48 ... for all other connections via filter thread M48x0.75/2"
♦ TSOAG9-EOS ... allows direct connection of Canon EOS DSLR cameras.
TSOAG9G2 - Mounts on cameras with protruding flash housing
The thumbscrews of the TSOAG9 collide with the flash housing. If you still want to use the off-axis guide 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.
