Thread: Declination Angle

I live at Location
What is the correct declination? Is there a calculator? I am using a polar mount on a 7.5 mesh dish.
Correct me if I'm wrong but the main bar in the middle of the mount, should that be set to my Latitude?

. . . and it's all discussed on
Using the lower table, I get about 3.866° .?.
See if that agrees with the other site Greg listed above. (I may have made a mistake) -
Other site says 3.87° , so we seem to agree.

I was wondering just how accurate does the declination and elevation angles have to be. But, since these are just starting points, both can be fine tuned to get the greatest accuracy.

in this order?
The declination is set correctly once, and left alone.
If you need to fiddle with elevation, check your LNBF centering on the dish.
Twist the mount on your pole to bring in the ends of the arc.
Don't forget to focus, and adjust the f/d (scalar).
Oh, and skew, too.

That's why spending a ton of dough on digital angle gizmos is a waste of time and money. Eventually you are going to discard them and get into tweaking and adjusting.
