Few days ago, I received my Celestron Focal Reducer F/6.3.
I tried it on my telescope Celestron 8″ SE, and i came out with good TEST shots.
Since it reduce the focal length from 2000mm to 1260mm on a Full Frame camera such as Canon 5D, 1Ds, Nikon D3,D700, and the most important thing is it reducers the Aperture from F/10 to F/6.3 by 37% for astrophotograhy purposes. I posted 2 pictures below of the Horse Head Nebula ( Barnard 33 ), Sirius, and Messier 3 ( M 3 ).
