You haven't said what type finderscope that you have. If it is a straight through one, you can improve your aiming accuracy by keeping both eyes opened. It's amazing how much easier it is to find objects than with only one eye.
Nonetheless, a red dot finder is still handy, especially for sparse areas of the sky. I have several Telrads and several small cheap so-called rifle ones. I use Telrads on bigger telescopes, the small ones on small telescopes.
The problem with Telrads is that you also need the cover for the glass, which stops it dewing over for an extra 10 minutes on bad nights, and then I use a 12V hairdryer on it. As I use the hairdryer on the smaller red dot finders.
I did once meet a chap with very good eyesight who claimed to have no problem finding galaxies with his Telrad alone, and had no use for his finderscope. Unfortunately, my eyesight wasn't as good as his.
You can hand hold one binocular tube behind a telrad, and get as good an image as in a finder.
