Focusing a camera at the prime focus of a SCT is quite difficult. I would suggest the purchase of a device called "Shure Sharp". This is an optical tool that you install in place of the camera, focus, then replace the camera and take the shot. Perfect focus ever time.

Note, the Shure Sharp only works for "deep sky" objects. It cannot be used with the planets.

Suggested vendor is: Spectra Astro Systems.
