Is it possible? With the standard Celestron parts, the distance from the reducer to the Canon T adapter is about 50mm. The Celestron OAG plus OAG to EdgeHD 8 adapter takes up about 55mm. Will I be able to focus both guide and dSLR cameras with a shorter T adapter? That seems iffy. Is there a shorter adapter I can get to connect the Celestron OAG to the reducer? That takes up about 25mm.
