Explore Scientific 2" Field Flattener for ED APO Refractors- Special Thin Nikon T-Mount

One of the truths of refractor optical design is a curved focal plane. While the center of the view remains crisp and clear the edges of that view become increasingly out of focus. Even the most precision ground optics will exhibit curvature but while this is typically not an issue for the observing astronomer - who's target is typically in the center of the field of view - blurry edges can be a huge issue for the astro photographer. With the addition of this field flattener, aberrations that are caused by this curvature are corrected! Your images will be tack sharp from edge to edge. Created using fully multi-coated optical glass to maintain optical integrity, the Explore Scientific will slide securely into the 2" opening of your telescope.

This model of Field flattener boasts the upgrade of an integrated T-Mount meant to interface one side of the flattener with a Nikkon Camera while the 2" aperture opening interfaces with your telescope. This makes it much easier and quicker to interface your Nikon camera with the Field-Flattener upgraded ED APO Refractor.
