I have The Sky (free version that I got awhile back with my old scope)) by Celestron
, but can not find the meaning of the abbrevition in any of the guides etc
, which I will put at the end of this message. I hope some one can illusidate me. It may be simple for you but I need lots of help lol.
So with out delay here they are:-
Parallax 33,600 mas. 2976119 pc
(Maybe 'mas' = Micro ArcSeconds
)
Magnitudes bt 2.003, vt 2.005
So; what is the meaning of the abbrev.'s of :-
" mas " and " bt " as well as " vt " ????
Thanks for the help. StevenA
