I agree that the double cluster is much nicer to look at when you can see both clusters. When I had a C9.25 I used a Lumicon Rich Field adapter (focal reducer) along with a TeleVue 2" diagonal and 27mm Panoptic eyepiece which gave a nice widefield view that framed the Double Cluster nicely. A focal reducer along with a 2" widefield eyepiece is really about the only way to do it with a scope that has that long of a focal length.
