If you use CCDIS the results might differ depending on the field you shoot and the orientation of the scope. I find 1mn exposure on a uniform starfield devoid of bright stars or only one bright star in the middle give me the best results.

For the initial alignment I do everything indoors with the ACT from Hotech. Much easier on a bench and you can fiddle to your heart content. CCDIS field to confirm only.
