Dear Brad, thanks for the comment.
Slowly-slowly, meditating over CP-300/U starfinder, I begin to understand why those scales are that way. (Because it is not a planisphere, we are supposed to look at it as if from the "outside" of the celestial sphere.) Most difficult part (for me) is imagining near-Equator southern hemisphere pictures.
Still can not comprehend the purpose of the "fat" black arrow near the bend of the cursor bracket...
Now I'm hacking a slotted ruler for placing Sun/Moon/planets. The scale is 1° per millimeter. What type of marker would you recommend for doing such marks? I'm afraid usual pencils will leave difficult to remove graphite dirt.
Regards,
Tony
