so for 3000 u will not get a good telescope
i understand that u have budget problems but please do not get tricked into buying a cheap telescope from some toy shop ( bangalore has many such shops )
i shall tell u some thing if ur looking for a telescope to view objects on land then u might as well go in for a binoculars
but if u want to do astronomical viewing then u must first tell me what u actuall want to do
i can provide u with tons of info about choosing a good scope for a good price but u must get specific do u want to do deep sky gazing. planetaary gazing,lunar gazing , solar gazing , astrophotography so u see this firstly classify's ur selection
