QHY
QHY cameras offer amateur astronomers a number of unique astrophotography cameras and accessories to choose from. Perhaps, the coolest and most innovative product is the new QHY PoleMaster! The QHY PoleMaster makes polar alignment easy. This is done by allowing an imager to assist with the polar alignment process. The result is a highly precise (up to 30 arcseconds) polar alignment in about two minutes!
