Meridian swap 1
Meridian looking south
Scope rotated to point at star on opposite side of meridian.
Use Maksutov to fine align target.
Tighten both right ascension and declination clutches to track.
Use slew controller to fine tune tracking.
Weight always below horizontal
Meridian swap 2
Meridian looking south
Tube always above horizontal
Weight always below horizontal
Loosen right ascension and declination clutches to slight tension (1/8th turn) and slew scope in declination to the north.
The general rule is “free the part you want to move. Grab that part.”
Use tube frame or declination arm as grab points.
