Main accessories for TSA-120

TSA-120 tube holder


The tube holder for TSA-120 is essential for the fixing of the tube on a mounting. It has the 2 holes for fixing on Takahashi mountings as well as Kodak screw pitch for fixing on a photo tripod. Moreover, it is equipped with a Kodak screw intended to receive a SLR/DSLR camera for a parallel connection.

TOA35-FL field flattener #80S with 50.8mm barrel


The TOA-FL35 field corrector allows you to obtain a flat field for imaging, on the 40mm of image circle. That makes it possible to cover most modern CCD sensors, without aberrations. See the TOA-FL35 system-chart above to know the assemblies available behind the flattener.

TOA35-RD focal reducer #18S F/5.6


The TSA-102 can be equipped with a focal reducer, giving the possibility for focal ratio to go from 7.5 to 5.6. Thus, you have a faster refractor, for wide field imaging. The reducer acts also as a field corrector, ensuring you a perfect flatness for imagers equipped with large sensors. The assemblies available with the reducer are available in the TOA-RD system-chart.


Camera angle adjuster (CAA) #6


The camera angle adjuster is a device that allows you to turn the accessories installed at prime focus of the OTA, in particular cameras for framing. This accessory has to be screwed before all the others at TSA-102 prime focus (see the general system-chart for more details). It is recommended only for the photographic use.
