The VC 200L is an 8" f/9.0 highly-corrected highly-specialized telescope for astro imaging. With its elaborate aspherical optical design it achieves an excellent image correction throughout the large illuminated field. (42 mm diameter fully illuminated)Astro ImagingThe VC200L is designed around Astro Imaging. Even at the edge of the 35 mm film format (larger CCD chips) stars are sharp (smaller than 15 micrometers). This is smaller than the resolution of fine quality CCD cameras which means that the telescope does not limit the image quality. With the recommended f/6.4 reducer you get much shorter exposure times.The basic configuration already contains a piggy-back camera holder. You can then take photos both through the telescope and using a telephoto lens parallel to the main instrument or you can use the VC200L for guiding while the camera sits on top.
