For best results:
1. Use your ED80 in the straight through mode (no star diagonal) at X100 mag. Make sure that the reticle cross hairs run N-S / E-W
2. Guiding(reticle) eyepiece should be an orthoscopic (for un distorted field).
3. For stars (20 degs. above the horizon) adjust the altitude on the mount.
4. For stars close to transit adjust the mount azimuth.
5. I have attached a list (C_stars.txt) of stars I use for drift alignment.
6. I usually start with transittting stars these are the easiest to use.
7. You do not need to use the SCP stars for initial alignment, many transit stars on the celestial equator are brighter and much more accurately placed and you do not need a polar alignment 'scope you use the main scope. Besides the main 'scope all you need is a spirit level and a plumb line.
