You can take wide angle images with just a camera and a tripod, with exposures up to around 2 minutes, depending upon the lens you use, and where in the sky you point it.
To take worthwhile images through any telescope you do need a tracking mount. It can be fairly basic, with just a simple drive
motor.
The camera is almost certainly not good for astrophotography, firstly
because 30 secs is not long enough. Secondly, smartphones are really
not up to to the task, if you are looking to take decent quality pics.
For less than the price of that camera you can get a Canon 1100D
DSLR, which is much more versatile and suitable.
Your present scope will do the job, but will suffer from chromatic
aberration [violet and/or yellow, fringes] around bright stars and the
moon.
Quality deep sky images are not easy to produce; I suggest that you
get a book on the subject. It's a long, steep learning curve, and can be
very expensive. Start simple, and persevere.
The Sony camera will do for basic phone camera use, but I think that
you will want to move up a step before too long. If you only want to
dabble, the Sony would do.
