Yesterday (04/24/2019), I received and installed the new Starizona SCT Reducer/Corrector II.
Note the diagram showing spot sizes, under Performance.
I think this development is significant since up to know I was considering swapping my NexStar 8SE for an 8" EdgeHD, with the 0.7x reducer, all very pricey, as you know.
What Starizona's new reducer/corrector does is combine both features (reducer and corrector) into one product and I'm very pleased with the results.
