You also have to ask yourself what you want to achieve with taking photos.
Will you be happy with an image that looks good on your screen to show friends or do you want to win prizes in competitions?
Once you have taken pics of the common bright objects with the wide field scope (~80mm refractor) where do you want to go?
To get prize winning images like you will see here (not by me
) requires dedication, expensive equipment and lots of time.
A cheaper option is to take science images like variable star estimates, supernova searches, comet astronomy, spectroscopy etc. Depends on your interests.
It's very nice to spend the dollars and get the stuff to take some pretty pics but you need to think what you will do after you've taken 25 pics of eta car and the orion neb.
