BANGKOK DEEP-SKY OBJECTS OBSERVING

---

Polar alignment:

The polar alignment is critical for circles setting the method of finding objects by setting RA/DEC and also critical for photograph observing. For star hopping method and visual observing, it needs just roughly alignment.

Finding the Direction

Polaris the pole star locates 1 degree from NCP (North Celestial Pole) (1 degree = two full moon). The pointer stars of big dipper (Ursa Major) point to Polaris. For bangkok, some time big dipper is under horizon, Cassiopia can use as pointer instead. For my observing site, I can't see Polaris which lies at 13 degree from horizon. Then I used compass which slightly away from the true North.
