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 (1/8 th 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.

Meridian swap 3 Meridian looking south Tube always above horizontal With right ascension and declination clutches still in slight tension (1/8 th turn), slew scope in declination to the north.

Meridian swap 4 Meridian looking south Tube always above horizontal With right ascension and declination clutches still in slight tension (1/8 th turn), slew scope in declination to the north.

Meridian swap 5 Meridian looking south Tube always above horizontal Slew in declination complete. With right ascension and declination clutches still in slight tension (1/8 th turn), begin slew of scope in right ascension. Weight always below horizontal

Meridian swap 6 Meridian looking south Slewing in right ascension. Use weight as grab point.

Meridian swap 7 Meridian looking south Slewing in right ascension. Use weight as grab point.

Meridian swap 8 Meridian looking south Slew controller swapped Use declination clutch housing as gunsight to rough align target in right ascension. Slewing in right ascension. Use weight as grab point.

Meridian swap 9 Meridian looking south Slew in right ascension complete. Begin slew of scope in declination to point at planet on opposite side of meridian. Use tube frame or declination arm as grab point. Use Telrad or scope frame to rough align declination to target. Weight always below horizontal

Meridian swap 10 Meridian looking south Slew scope in declination to point at planet on opposite side of meridian. Use Telrad or scope frame to rough align declination to target. Weight always below horizontal

Meridian swap 11 Meridian looking south Slew scope in declination to point at planet on opposite side of meridian. Use Telrad or scope frame to rough align declination to target. Weight always below horizontal

Meridian swap 12 Meridian looking south Scope rotated in declination to point at planet 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 17 Meridian looking south Slew controller swapped Use declination clutch housing as gunsight to rough align target in right ascension. Slewing in right ascension. Use weight as grab point.

Meridian swap 18 Meridian looking south Right ascension slew complete. Begin slewing scope in declination to point at star on opposite side of meridian. Use tube frame or declination arm as grab points. Tube always above horizontal Weight always below horizontal

Meridian swap 19 Meridian looking south Tube always above horizontal With right ascension and declination clutches still at slight tension (1/8 th turn), slew scope in declination to point at star on opposite side of meridian.
