Thanks JJ and Trevor.
I must add, although the off axis/flip mirror is a great concept the design leaves me a bit dissapointed. With only one grub screw holding the front and rear, where the camera attachment and 2" fitting to slip into the focuser are. Each of them have to be Very tight, otherwise the camera can fall off. Thankfully now I always have the camera with its strap secured to the rear of the scope. So If it falls, will only swing in mid-air without hitting anything. I am thinking of glueing the front and rear sections to the unit. This will mean I have to rotate the whole set-up to find a guide star.
Why such a well thought out instrument has to have just this small oversight. To have added 3 grub screws to the front and rear would elliminate any camera falling off.
Here is a link to the device I am using.
