Well ...
Those scopes are so small I'd pick it up, tuck it under one arm and use like binoculars and sweep the sky to find things. With practice you'll get the hang of it.
The old mechanical solution was an equatorial mount with setting circles, on the basis you knew how to accurately align it with the South Pole and set the ra circle to read correctly. From there you find the position of objects from an atlas and dial them up, if you get it right. Few manage to do it this way. It's a fair challenge and impossible for some.
The optical options are:
- a simple sight consisting of a small ring at the top of the OTA and a dot or dimple at the back, line your eye up on these;
- finderscope, possibly a 90 degree one;
- red dot finder,
- telrad or similar.
Electronic solutions:
- encoders and software working as "push to"
- GOTO mount.
