Think
I've marked the base on my Parks dob in 10 degree increments (only temporary ..masking tape +texta..that was 5 yrs ago) and a protractor on the alt.
These help greatly for refining the area in my search and destroy missions.Very rarely do I not view from the same spot in the backyard so the alt doesnt change .For the az I align a star and move the base to suit the star.
Then you only need a list of objects az/alt coordinates for your location and time and of you go.
I'll check the links on that page and I might get off my butt and remove the tape and fit a more refined fixture .
Thanks
