Works Well with Sharpstar 94EDPH
31 October 2022 | Melissa
I purchased this flattener to use my 94EDPH at its native 517mm (or so) focal length. I had tried a couple of other flatteners that left noticeable field curvature in the corners. The Esprit flattener has only a slight distortion in the corners, and this looks to be more a factor of imager tilt vs. the flattener itself.
The only issue I faced is both the flattener and the 94EDPH focuser have female threads, so I had to purchase a custom adapter. Overall, though, I can recommend this flattener.
