OK, we should be able to get the finderscope ("spotter") to work better - but even on more expensive scopes, they can be poor performers.
Best if you continue until you can get the best out of existing equipment, then you are in much better position to understand what the best upgrade path will be for you.
Send me a PM (private message) if you'd like me to have a look at your scope. Aligning the finderscope is best done during daylight on a very distant object like a mountain top or TV transmission tower.
