6.3 Focal Reducer-to-2" Assembly for use with 80ED-APO and 300D Digital Rebel

NOTES: This works great!  See my image of NGC2244-Rosette Nebula: http://www.gvtc.com/~mhowell/NGC2244-345m-Sharp-ADPADD.jpg

3.3 Focal Reducer on 10" F10 LX200 w/300D camera NOT Recommended.

NOTES: (Image of M31) Severe vignetting and coma result because of the combination of large CMOS sensor with the 3.3 focal reducer.  The 3.3 focal reducer was designed for much smaller CCD chips that don't utilize the outer perimeters of the reducer.
