Con Astrotortilla si può verificare in tempi molto rapidi se l'allineamento polare è buono:
4.3.2 Polar Alignment
Using a plate solver eliminates the waiting that's distinctive in polar aligning your mount with the traditional drift
method. Just solve a frame, turn the scope along RA and solve again. The dierence in solved declination values
is equal to the amount of drift in declination observed when tracking a star for a time equal to the amount turned.
A tedious 20 minute drift can now be done in way less than a minute!
A pair of frames shot at the east/west meridian is used to determine the altitude error of the polar axis, and a
pair shot at the southern meridian (assuming northern hemisphere observation) gets you the azimuthal error.
To use the tool, select Tools ! Polar Alignment. Choose the correct hemisphere and point your mount roughly
at the meridian to measure azimuth error or to the east or west to measure altitude error.
Then press the according button to let AstroTortilla shoot and solve the pair of frames. When done, your polar
alignment error in degrees is shown on the screen. Use this to correct your alignment by turning the alignment
knobs on your mount.
When measuring azimuthal error, be sure not to point within a half a degree or closer to the meridian to avoid
meridian
ips! Pointing on the west (right) side of the southern meridian is the safest bet.
Note: With clever choosing of pointing direction and some spherical geometry, the polar alignment
Il metodo sembra interessante per capire quanto è corretto l'allineamento polare, ma non aiuta a correggere.
Su questo APT è molto più avanzato poiché ti indica con LiveView la posizione dopo mettere la stella. Se non erro è praticamente uguale a quanto fa il firmware della Synscan.
