What is the difference between these 2 methods to adjust declination ? (CM 1.2m polar mount)

The bottom one sets the acuteness of the arc, declination and the top one adjusts the inclination, how high the dish is pointing.

Yeah they are two different things, inclination and declination and work in tandem with each other.

Ok thanks!
At moment my inclination and skew is perfect for 4.8e (due south satellite) But when dish is moving to west on 8W for example, I need to manually adjust skew (just a little bit). Does I need to adjust the bottom one ? (In the red circle on my picture )

Some satellites have non-standard skew, which won't necessarily line up with the motorised LNB phase... annoying but true.

The best setup would be with a motorised feed, but obviously it is complicated and expensive.

Yes, from my location I can lock all satellites from 52e to 30w with a sufficient signal (only 25.8e missing with my CM 1.2m ) just 7w and 8w need a fine skew tuning
