hi leon,
like you i made my own wedge and i polar aligned using the autostar alignment on the start up menu . All you do is align your wedge roughly by placing the telescope in the equatorial home position (90degrees), then pointing the scope in azimuth to compass south +or - the magnetic shift from true north ( consult ordinance maps of your area or find on web). then set up the autostar as normal and select one star alignment . the scope should attempt to slew to sigma octanis. look through the low power eyepiece and try to identify sigma octanis in the field of view. their should be a pattern of stars in the field of view that contains sigma octanis ( look up one star alignment on the web to find a reference) having identified sigma octanis centre it using azimuth and elevation adjustments. repeat one star alignment several times until sigma octanis is centred in your gotos. I am able to take unguided pics for up to 2.5 minutes with noticeable star drift in only 1/3 of my shots and thats only due to pec error. the rest of the shots show nice round star images. i think this is the easiest alignment method for a wedge and it seems to work fine.
regards philip
