Gary,
That thought has crossed my mind although I prefer to be able to remove the guide scope from the 10" when I move it around as it is at risk of being knocked off when I carry the gear inside at the end of the night. I'm also unsure whether the 40mm aperture will make it difficult to find a guide star in some shots. My tests so far have been with the Neximage and I've chosen bright objects. I've now mounted it on a Losmandy bar and will try it side by side tonight. If that works then I might look at getting a larger diameter finder - something like an 80mm Stellarvue.
