Description

To fit the field of view of my f/3.4 12" Newton (with 3" 0.85x ComaCorrector) on Sony full frame to my ASI 294mm pro I tried a Viltrox 0.73x Speed-Booster. This results in 744mm focal lenght at f/2.4, almost an RASA.... Coma is present (still have to improve the distance of the Speed-Booster) but BlurXTerminater elimintes that almost perfectly....
