Page 21: Polar Alignment
Instruction Manual Polar Alignment The Polar Alignment Viewfinder Normally, a rough alignment with the celestial pole is sufficient for visual pur- Reticle LED poses. However, for those observers who need to meet the more demanding knob requirements of astrophotography, the polar alignment viewfinder allows the telescope mount to be more precisely aligned with true North. -
Page 22: Polar Alignment By Using The Polar Viewfinder
Instruction Manual Observers on the northern hemishere: N- 7 a) Determine the rough longitude of your observing site (example: Munich is 12° E). Now determine the longitude of the time meridian according to your local time. For the central european time, this is 15° E (do not use daylight sav- ings). - Page 23 Instruction Manual Observers on the southern hemisphere: S- 7 a) Look at the trapezoid association in the polar viewfinder’s reticle. They build the stars Sigma, Tau, Chi and Ypsilon Octantis. Turn the RA axis until the “real” stars roughly cover the edge points in the trapezoid figure. S- 7 b) Probably both trapezoids may still be parallel shifted.
