Title: Useful for astrophotography!
Review: When you take a long exposure photo whith a motorized camera the batteries drain whith the first picture (four hours exposure aprox.), and you wasted 8$ or more, whith this baby you take four cheap AA batts and take the same photo for less $, the recargeable NiMh batteries are the best choice, i take a three hours and a half exposure whith this ones. For last, Adorama ship is fast and very good package!
