Try before buy
So come to some star gazing activities and see which brands / models are there as choices. Forum (e.g. here), star camps organized by societies (e.g. HKAS) have some people around who are the local dealer of scopes and equipments.
Usually a pair of binocular is good for beginner, usually 7x50 (7x - magnification / or we call "zoom" ; 50 - diameter of the objective lens), of course depends on your budget too. This is good for some deep sky objects like nebulae, clusters and can be your life-long partner.
Apart from a similar binocular, I also own a small J-brand (J for japanese null brand) 8cm f/7 refractive telescope (8cm - diameter of objective lens ; f/7 - focal ratio, i.e. the focal length of the objective lens is 8cm x 7 = 56 cm), of which I use to watch / photo the moon / the Sun. Of course there are much more better options. Come to star camp and find out !
