I am a vey keen newby at ASTRONOMY, with a 10" dob. reflector. Have downloaded lists of items of interest to examine with the RA and Dec details and have looked at numerous articles on the subject, but have a problem with understanding RA, Dec is OK.
I understand the comparison with longitude and RA, but how do I find a listed object e.g. NGC104 47 Tucanae at RA 00 24.1 and Dec -72.05.
The 0 point is where the vernal equinox occures and you move east by hourly intervals, 1 x hour = 15o but unless you know the exact vernal equinox point how do you know where to look, especially when it all changes by the hour.
Is this navigation system only for equatorial mounted scopes.
