When doing astrophotography with refractor-type telescopes, the faster the focal ratio the more field curvature becomes a problem. Field curvature will appear in the corners of astrophotographs, making the stars smear perpendicular to the axis of the image. This is called coma -- coma is Latin for comet, because the stars look like comets. The more the curvature, the closer to the center the coma appears. The larger the sensor, the worse the coma.

The ED152 Air-Spaced Triplet FCD1 Series in Carbon Fiber with 3 HEX Focuser represents perhaps the greatest value in a large aperture ED Apochromatic refractor available today. The 6-inch f/8 optics produce diffraction-limited images producing high resolution images of planets and deep sky objects.
