Otherwise known as the question of, "How long is a piece of string?" I shall start by making some general comments and then move on to the particular, but restrict the issue at this point to the question of optical equipment.
Astronomy is an almost unique field of endeavour, in that you literally do not need to spend a cent to get started. You can just go outside and use your eyes, reference the public library and talk to people for information, enlightenment and enjoyment. On the other hand, the sky is literally the limit: whatever your means, you can spend it all and still think of other stuff that you desperately "need".
If you are asking this question earnestly, the sensible first step would be to assess the following, which will determine your approach:
Honest appraisal of the above will pay dividends, and you will be much happier in the long run to take the time to do this, rather than rushing into unwise purchases. (This caution should not of course be allowed to dampen your enthusiasm.)
If you have lots of spare cash, only modest requirements, or subscribe to the Californian ethos (I want it, I want is ALL and I want it NOW), then by all means go out an spend. But you will still be advised to consider the above list in order to make a wise decision. Since you are reading this, it should be possible to post more specific queries on this forum and get sensible answers. You are nevertheless urged to visit the Society and talk directly to people, as whatever you are contemplating purchasing, there may be someone with direct experience who can advise you. There is nothing like a lively discussion to probe the merits/demerits of a prospective purchase.
This is the acquisition advice I cna offer to start off with:
Well now, what are your specific questions?
Cheers,
