William Optics 2" 0.8x Reducer / Field Flattener 6A for GT102 Telescope # P-F6A-GT102
William Optics GT102 Reducer/Flattener
I purchased the William Optics GT102 reducer/flattener for use with an Explore Scientific ED 102 F/7. Coupled with a Canon EOS T5, image is correct across the entire field with no vignetting. I could not be happier with the results.
