Model: skywatcher_flattener_esprit_100_20188Part Number: 20188
An optically-matched M48-fitting doublet field flattener for Sky-Watcher's Esprit 100 ED PRO triplet refractor.
The M48 fitting provides a large clear aperture to reduce halation. A precision thread ensures the triplet and doublet lens groups are precisely aligned on the optical axis perpendicular to the image.
The Esprit-100's imaging circle is 40 mm when used with the field flattener.
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.
