253 is a fairly large object with a relatively low surface brightness.
Its quite easy to see in your finder or with binoculars, and harder to find panning around looking for it .
Theres a couple of nice bright planetary nebs visible, ngc3132, and ngc2438, well worth a look.
If you have Cartes Du Ciel, (a great freeware chart proggie,) theres a freeware addon called rtgui, which allows you to search objects by class, magnitude etc, and even suggests lists of the best objects currently visible given your search criteria. It then opens a chart for the object you selected.....brilliant !
