I've added the Starizona 6.3 Reducer/Corrector II to my imaging arsenal for my C8 OTA and ZWO 294 mc one shot color camera. It produces sharp, clear results with 2 -3 minute exposures that are about 3.5 times the image size with HyperStar. It seems ideal for objects 20 arc minutes and under. Objects like the Dumbbell, Wizard, Bubble and Helix fill the frame perfectly. I did go to off-axis guiding which resulted in nice round stars. I also use the Virtual View back for easy rotation which you often need to find a guide star and get the best object framing.
