Welcome to IIS
A couple of points:
- If you have to observe from a balcony then expect some vibrations in the view. People go to great trouble to remove this by installing pier mounts but if you are just putting it down on the balcony expect the scope to vibrate every time you move. This will get worse the higher the magnification of course.
- The advice to cool your scope is essential BUT, again, if you are observing from a balcony (fair bet its concrete) it will be hot and cause thermals that will cause degredation of your image.
Final message, try to observe from a grassy area and avoid observing across hot roofs as they give off thermals as well.
Good luck
