Just generally speaking, the moon doesn't need big aperture as it's pretty durn bright. In fact it is common to put caps with a smaller hole on the scope to kill some of the photons.
For close ups you will need a longer focal length and a webcam to take videos which are then stacked (AviStack eg ) to overcome the instability of the atmosphere which will turn your single frame shots into mush. Similar for planets as well, bright and small so focal length and webcams is the best option.
DSO's etc respond better to big apertures and long exposures which are still stacked. Guiding becomes the big issue then and a good mount and system is the answer.
