TOA-RD F/6 reducer #18S F/6
The TSA-102 can be equipped with a focal reducer, giving the possibility for focal ratio to go from 8 to 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.
