50 f / 1.8 is a good lens for night photography. It is not as wide as 24-240, but it is lighter in color.
Unfortunately lenses for sony are quite expensive.
Your camera allows you to change lenses. You can choose a light wide-angle manual lens. For landscapes, autofocus is not very important, but the price can be budget
24-240 3.5 will require long exposures at night. On the other hand, if we are to shoot a landscape, then the aperture is still covered up to 10-16 even at night. This is not very good for starry sky photography, but terrestrial pictures will be quite interesting.
Congratulations on your new lens, good purchase!
We are waiting for beautiful photos from you:))
