Good luck Suzy .. time and practice will get you there!!
If in a dark site, push ISO 1600, 18mm, for 35 sec or so. As I said on FB, focus can be tricky, so good luck there too.
I have the adapter to attach to scope but the Moon is the main object here, maybe a planet or 2, but you will need tracking to capture nebula.
Down the track you will have to tackle stacking and processing, which I am not good at (= hopelass).
The pics here are single images - no stacking, and minimal processing - alter brightness and contrast only.
