triangulate as it seems. i pick 3 stars around where the object should be and sync on those stars then I slew to the object take a 3 minute guided photo once its come though stretch the buggery out of it to see whats there .

To give you an idea of what happens when your polar alignment is actually spot on. I went out for a deep sky trip over the weekend, Friday night i set up my scope, alls well without any syncs i was able to put stars on the CCD sensor from north to south east to west. with 2 syncs i would drop it within 5 minutes of the center of the ccd. Saturday I pulled the scope off the mount because i wanted to do some modifications, I put the scope back on the mount. and same thing as friday night. 1 sync and i was getting pretty much perfect pointing.

When doing my guiding calibration it would land back directly on the same pixel which means no drift at all. Aim for this level of accuracy and your images will take a massive step up in the world!
