Hi,

I'm having a great deal of difficulty in collimating my DSI RC10C scope using the stars. I don't have any eyepieces so have to use a camera which adds to the difficulty. I have an Artificial star that I can use but can't find it in the scope. Does anyone know what distance (approx) would I need to place it to be able to focus on it. The scope is 1854 fl, aperture 250 with the secondary obstruction 50%. and the focusing is done by moving the secondary. I will have to go 'mobile' somewhere but would like a suitable distance before I go.

Thanks
Charles
