Large Format Imaging with the Ceravolo 300 Astrograph
 |
Featured on this page are a few images taken during a December 2007 test imaging session. The Ceravolo Astrograph and the large format, 4096 x 4096 x 9 micron pixel, Apogee U16M camera yield a huge field of view covering 1.4 x 1.4 degrees of sky. Other than the Rosette Nebula images, no special processing has been applied to these images. Nor have they been flat-field corrected to eliminate the CCD's dead column and the 13% vignetting at the very corners of the frame. At left, the Ceravolo astrograph is bolted to an Astro-Physics 900 GoTo mount - a great combination. The guide scope is a 3" reflector we made for a project long ago, and the guide camera is the Orion StarShoot II with a monochrome chip. Strapped in place is the prototype focuser/thermal control unit. |
