I drew this up in LibreCAD a week or so ago for kicks.
After seeing a picture of someone's spinclination mount, that had a Latitude scale on it
for setting the declination. Thought it might be useful to put on a mount / pole so I can judge how much I am spinning the mount on the pole when fine tuning alignment. Should last a little longer than chalk marks.
PDF here, invert the color so it prints white on black.

and here is what it looks like on my BUD pole.

Looks good. Is this mostly for C-band? With the Stab 90 motor on KU band there is no declination setting. The motor adjusts for declination and skew.

yeah, for the BUD. Just wanted some means to get me back to where I was when adjusting. Reality is, if you are adjusting the North/South Axis by spinning the mount slightly on the pole, ya normally only need to move it by about a mm. which is tough to do when it weighs so much.

All tracking polar mounts for satellite have a declination adjustment that must be set correctly once when at your zenith satellite. It is essentially how much the dish is tilted downward to ensure it's staring at the clark belt above the equator instead of in to deep space, and varies with Latitude. That is what you are accounting for when you set the little diseqc motor's 'latitude' adjustment. Here is a better explanation.

MajorTom I see you have an organic obstruction south of your antenna that may require pruning...

LOL, yeah that's a neighbor's well kept tree.
There's actually three of them. None of those get in the way of anything though as you notice they are north.
