    Re: Stellarium Program as practice tool

    Hi Zane, in Stellarium you can set your viewing location by lat.long and set your height above sea level.  Because you can set your height above sea level I presume that the dip correction must be applied unless Stellarium is taking that into account.  When Stellarium uses the term "apparent" altitude I accept the altitude of the object includes atmospheric refraction and so I presume that the main correction is needed.  I am not sure about either of these assumptions and that is why I am asking.  I do understand that if I use the sun or moon I will have to accound for the semidiameter.
